There are two kinds of serial devices defined by EIA standard RS-232C. Data terminal equipment (DTE) is a definition for a 'dumb terminal'. Data communications equipment (DCE) is a definition for a modem. The modem cable above is for a connection between DTE and DCE. If you will be connecting a PC (DTE) directly to a host computer port (DTE), you will need a null modem cable which has the pin definitions switched.

PC-PLOT-IV Appendix B

Appendix C Terminal emulation commands

The following section describes the commands sent by the host computer to perform control/data functions for the various terminal emulations performed by PC-PLOT-IV.

It is important to note that the user, in most circumstances, will not be able to enter the listed commands from the keyboard and have the same effect as listed below because the command processor in the host computer usually will not echo escape sequences back to the terminal unaltered. The only time when commands may be entered locally to test them is when local keyboard mode is entered (ALT-4).

The information, while listing each command, is not a complete description of each command. For a complete description of all of the commands, the user is referred to the following user manuals:

Tektronix 4010 Terminal User Manual
Tektronix 4014 Terminal User Manual
Tektronix 4027 Terminal User Manual
Tektronix 4105 Terminal User Manual
DEC VT-100 User Manual

DEC VT-200 User Manual

Digital Engineering VT-640 Users Manual

PC-PLOT-IV terminal emulation has two distinct operating modes with several sub-modes.

1. Hardware_ Alpha_ Mode

a. VT-100 Mode

b. VT-200 Mode 7 bit controls

c. VT-200 Mode 8 bit controls (not implemented)
d. VT-52 Mode

2. Line drawing mode

a. Tek 4010/4014 Mode
          Line drawing
          Point plot mode
          Incremental point plot mode
          GIN mode

b. Tek 4027 mode
c. Tek 41xx mode

When the terminal emulation is first loaded, it is in VT-100 alphanumeric mode. In this mode, the terminal sends and receives ASCII characters and displays them on the screen which displays hardware generated characters and scrolls.

Mode Shifts

The shift between graphics and character mode is basically automatic. The major mode shifts are shown on the chart at the beginning of this section. The shift between major modes is also shown in the table below:

                    Tek 4010 to VT-100                       ESC FF (lb, Oc hex)
                     VT-100 to Tek 4010                       GS (ld hex)
                     VT-100 to Tek 4010                       ESC [ 38 l (lower case L)

Tektronix 401014014 Commands

There are three basic type of commands that the Tektronix 4010 terminal responds to. They are standard control codes as defined in the table below, graphics transition sequences, and escape sequences.

The DELETE character (7F Hex) is a legal x,y coordinate value and is allowed in a graphics string only. If the graphics mode is not active, DEL characters will be ignored. Delete characters can optionally be ignored in graphics records also. If the host sends a DEL code at the end of each record automatically, it will send the pair ESC ? to substitute for the delete code.

Some systems send either <NUL> or <SYN> (00 or 16 Hex) as fill characters since the average data rate to a Tektronix Model 4010 cannot exceed 300 baud. These characters are also stripped out.

XY data format

Line drawing mode and point plotting commands are encoded into printable ASCII characters in the range of 20 hex to 7f hex.

Line drawing mode involves the concept of the Current Point (CP). CP is the present XY location of the drawing cursor on the virtual 1024 x 1024 Tektronix screen. A MOVE command sets a new value for the CP and a DRAW command draws a line from the CP to the endpoint of the line which becomes the new CP.

XY data consists of 4 or 5 bytes which are encoded so that their value is a printable ASCII character. Four byte strings have a resolution of 1024 x 1024 (10 bits, Tek 4010) and five byte strings have a resolution of 4096 x 4096 (12 bits, Tek 4014). Data is sent in the following order:

HI-y LO-y HI-x LO-x 4010 format

HI-Y LO-Y LOLO-y HI-x LO-x 4014 format

In both cases, the LO-x byte is the indicator that a complete data record has been received. After the first group of data bytes are sent, only the ones that changed need be sent to save on data transmission time. The LO-x byte must always be sent and if HI-x changes, LO-y must also be sent.

The data encoding of the sequence is as follows:

Y9 Y8 Y7 Y6 Y5

HI Y BYTE

Y4 Y3 Y2 Y 1 YO

LO Y BYTE

X9 X8 X7 X6 X5

HI X BYTE

X4 X3 X2 X1 XO

LO X BYTE

The following sequence of PLOT-10 commands describe the two types of operations available- Move and Draw.

@ (40H) X 1 0 0 0 0 0 0 lo x=00000

US (1FH) X 0 0 1 1 1 1 1 end graphics

There are 10 bits in each address allowing for a resolution of 1024 x 1024.. The first command following a GS is always a Move to an absolute X,Y location. The following bytes are all a draw from the current position to the new X,Y location until another GS is encountered which signals another Move command or a US which is the end of a graphics sequence. A graphics sequence may also be terminated by a Carriage return or an ESC FF.

GIN Mode

GIN mode provides a method by which the host computer can obtain status and crosshair cursor location from PC-PLOT. In order for GIN mode to be active, the screen must be in graphics mode already.

When GIN mode is active, the bypass flag is set and all characters received by PC-PLOT-IV are ignored until the bypass flag is cleared. The control codes below describe management of the bypass flag.

PC-PLOT supports all three GIN mode functions which are defined for the Tektronix 4010/4014 terminals.

Mode 1- Alpha Cursor Position Report

GIN mode 1 reports the present position of the drawing cursor in row/column units. The position returned is where the next character would be drawn on the graphics screen. The cursor position is updated every time a graphics MOVE or DRAW command is executed. Six or 7 bytes of data is returned by a mode 1 report.

Mode 1 invoked by: ^rESC ENQ (lb hex, 05 hex-from host)

Characters returned:

Status: 20 for graphics, 24 for alpha

Mode 2- Immediate report of graphics cursor

Mode 2 GIN reports the current location of the graphics cursor in x,y units (1024 x 780) to the host without any operator intervention.

Mode 2 invoked by: ESC SUB ESC ENQ

(Ib hex, la hex, lb hex, 05 hex-from host)

0 0 1 0 0 <EOT> (optional)

byte 5

byte 6

Mode 3- Interactive report of graphics cursor position

When GIN mode 3 is entered by a command from the host, the crosshair tracking cursor becomes visible at its current location. When PC-PLOT starts up, the default

location for the crosshair cursor is the center of the screen. The cursor is a small cross made up of 10 x 10 pixels. The crosshair cursor can be moved by two methods; the keypad keys and a mouse. The cursor arrow keys on the keypad (2, 4, 6, 8) move the cursor down, left, right, and up. The 1, 3, 7, 9 keys move the cursor in a diagonal direction.

When PC-PLOT starts up, each press of a cursor key moves the crosshair cursor by one pixel. Depressing the SCROLL LOCK key once will cause the cursor to move 8 pixels every time a key is pressed. Depressing SCROLL LOCK again will select slow mode.

PC-PLOT remains in GIN mode until an alpha/numeric key is pressed at which time PC-PLOT sends a report to the host and exits GIN mode which turns off the crosshair cursor.

Mode 3 invoked by: ESC SUB (lb hex, la hex-from host)

Characters returned:

byte 1

Tektronix 4027 Command Definition

A subset of Tektronix Model 4027 terminal commands are included in PC-PLOT-IV.

The following command shows the basic format of a 4027 command. Each command is preceded by an exclamation point followed by a three-letter command and parameters if necessary.

4027 Command Construction ------------------------

<!>COM parm,parm,parm,parm,parm,parm <cr> I I i I I I I I--sequence terminator I I (----------numeric parameters for command I I--------------command

I-------------=---4027 command lead-in character

The leading character for the sequence is the ASCII

exclamation point (Hex 21).

If the terminal emulation is in Alpha mode AND the PC-PLOT graphics screen is turned on, reception of a <!> character

will cause the command parser to look for a valid 4027 sequence.

The command character and terminator shown are the default values-other ones can be defined under program control.

No spaces between the command character & command keyword

Parameters are separated from the keyword and other parameters by separators which may be a comma or one or more spaces. The separator between the numeric parameter and the keyword or between a numeric parameter and

a neighboring alphabetic parameter may be omitted.

Parameters may be numeric, strings or words. A parameter . word may be abbreviated to its first letter.

The last character in a command is a terminator which can be a semicolon, carriage return, or another command character. If the command is the final string in a line of text, the term. is a cr. If a command is followed by

text, the term. is a semicolon. If the command is followed by another command, the command term. is the new command character.

String delimiters-some commands accept delimited ASCII strings. Legal delimiters are:

- ' ' ; , cannot be used as a delimiter

VT-100 Keypad Definitions

The complete VT-100 keyboard can be emulated on the IBM PC keyboard with some compromises. The compromise is the placement and arrangement of the 16 key "keypad array" on the right hand side of the DEC keyboard. There is no similar arrangement on the IBM-PC so that the functions of the keypad are generated using the function keys F1-F10 on the left of the IBM keyboard.

The arrangement, while not the easiest to visualize is the closest that we could come to completely emulating the VT-100 keys.

PC-PLOT-IV Plus has a program module named KEYDEFI.COM which will redefine the keyboard so that the new IBM enhanced keyboard looks like a standard DEC VT-100. The redefinition module is described more fully in appendix G. VT-640 Commands

The Digital Engineering VT-640 conversion of the DEC VT-100 terminal utilizes all of the DEC ANSI commands, all of the Tektronix 4010 commands plus a few defined specifically for the conversion. PC-PLOT-IV includes some of the added commands.

These additional commands allow PC-PLOT-IV to be used with Molecular Designs Limited MACCS software.

	Command Meaning

	SYN Shift to transparent mode (4010 alpha)
	ESC "Og Shift to transparent mode
	ESC "4g Crosshair cursor on (same as ESC SUB)
	ESC /Od Normal draw-points on
	ESC /ld Undraw mode-points off
	ESC /2d XOR new point with screen

Appendix D HELP Compiler

Introduction

PC-PLOT-IV includes a 25 section help file which provides additional assistance to users on-line. It is possible for users to change the help file or add to it for their own unique system requirements.

A large user of PC-PLOT-IV may want to eliminate most. of the general help and write their own help file for their on-line users. The PC-PLOT-IV HELP compiler is used to convert straight text files into a help file that the HELP command in PC-PLOT-IV can utilize.

Format of HELP text file

A help text file is made up of several elements. The first section of text is the HELP menu which lists the topics available by number. The balance of the HELP text file is made up of text which will fit on one or more screens.

Each section of the HELP file is terminated with an accent mark (reverse apostrophe) ( ` ). If there is more than one page to the help topic, separate the pages with a left curly brace ( { ).

Example text

HELP file example

1. Help on loggin in
2. Help on logging out
3. Help on mail system
4. Help on graphics

5. Help on searching

Topic 1 First Help Screen
.... text of screen .....

... text of screen ......
Topic 2 help screen
Topic 3 help screen
Topic 4 help screen
Topic 5 help screen

Using the HELP compiler

The HELP file compiler reads the file that you create and reformats it so that it can be used by the PC-PLOT-IV HELP command. To run the compiler, follow the instructions below:

C>TEXT<cr>

	Name of input text file ..........HELP.TEX<cr>

	Name of output text file .......... PCPLOT.HLP<cr>

	Number of text segments ........... 27<cr>

	C>

The name of the input text file containing your HELP file text can have any name. The output file MUST be named PCPLOT.HLP. You must also specify the number of text segments in your file for the compiler to work correctly.

The number of segments is equal to the number of topics plus one for the initial menu. The file PCPLOT.HLP is an ASCII file with a header record appended which has a pointer to the start of each of the text segments.

PC-PLOT-IV Appendix D HELP Compiler

Appendix E Wyse WY-700 Notes

PC-PLOT-IV assumes that the COLOR jumper on the WY-700 is installed. If you are unable to get any graphics drawing on the Wyse board with PC-PLOT-IV, you may have to enter the command:

	MODE C080<cr>

The mode command will set up the registers in the Wyse for use with PC-PLOT-IV.

PC-PLOT-IV Appendix E-Wyse WY-700 Notes

Appendix F Mouse and Keyboard Remapping

Mouse Drivers

PC-PLOT-IV no longer contains a mouse driver. It relies on a driver supplied by the manufacturer of your mouse which provides a interface compatible with the Microsoft mouse.

	The following mice have been tested by Microsoft Systems:

		Mouse Systems PC Mouse (optical) Microsoft Serial Mouse Microsoft Bus Mouse
		IBM PS/2 Mouse

It is necessary to load the mouse driver before you run PC-PLOT-IV. If you have selected the mouse option in the ALT-S setup menu as YES, the message < Looking for Mouse Driver at INT 33 hex >. If a mouse driver is found, it will be used in GIN mode.

The status of the mouse driver flag is displayed in the ALT-8 screen on the next to the last line.

Keyboard Redefinition

PC-PLOT-IV Plus includes the necessary code to implement keyboard remapping if a second program, KEYDEF is used. The KEYDEF program will be available in first quarter 1988 for registered users of PC-PLOT-IV. Avai;ability of the keyboard redefinition will be announced in the first quarter 1988 "Terminal Emulation News".

To remap the keyboard, you must run the program KEYDEFI before you run PC-PLOT-IV Plus.

KEYDEFI does not interfere with other keyboard enhancement or POP-UP utility programs.

KEYDEF is made up of two modules: the program KEYDEFLCOM and KEYDEF.DAT which is the key redefinition file. A user can modify the KEYDEF.DAT file to completely redefine the entire keyboard. Each key can send either a single ASCII character, a string of ASCII characters, an extended keyboard scan code, or a null code. KEYDEF is designed to accommodate keyboards which have up to 128 keys. All combinations are available for all keys, normal, shifted, ctrl, and ALT.
