What Is PC-PLOT-IV |
|
|
| |
|
|
| PC-PLOT-IV is the ultimate
in terminal emulation software for your IBM Personal Computer. It includes
Tektronix 4010/14/27 graphics terminal emulation, DEC VT-100/200 (ANSI
X3.64) terminal emulation, and selected features of the Retrographics |
| conversion of a VT-100
(VT-640). PC-PLOT-IV+ (optional) includes Tektronix 4105 terminal emulation. |
| |
|
|
| PC-PLOT-IV includes
a comprehensive on-line help file that lists twenty-five different topics
related to on-line use. Each topic contains one to 4 screens of specific
instructions on using the many features of PC-PLOT-IV. The help text file
is user-configurable so that specific help can be created for a user's
operating environment. |
| |
|
|
| Local keyboard commands
will send a true break to the host, disconnect the modem, toggle local
echo, manipulate upload/download files, redial the last number, draw a
picture file, stop screen output (no scroll), toggle current color palette,
turn printer |
| on/off, execute a script
file, enter PC-DOS mode, clear screen (and insert page break while saving
a file), send 'here is' (answerback message), enter local keyboard mode,
and edit any of the setup files. |
| |
|
|
| The communications manager
portion of PC-PLOT-IV allows up to eight different terminal configurations
to be saved in a disk file for instant setup of your most-used configurations.
An on-line telephone directory of up to 16 names, numbers, and login |
| sequences is included
for ease of access when using a modem which supports autodialing. |
|
| |
|
|
| A script language allows
automatic logon to your remote host. Using the script language extends
the number of setups available and completely automates the process of
logging into a computer system. |
| |
|
|
| Up to 20 prestored text
strings can be defined for the function key array for commonly used keystrokes.
The strings can be up to 76 characters long and can include control as
well as alphanumeric characters. |
| |
|
|
| ASCII (text and picture)
files can be sent from the host computer and saved in a disk file for later
use by other utility programs. Files stored in a disk file can be sent
to the host either a line at a time or as a continuous stream of characters
depending upon the setup of your host computer. |
| |
|
|
| Files can also be transferred
to and from the host using the XMODEM protocol which will correct errors
caused by noise on telephone lines. The original XMODEM protocol was developed
by Ward Christensen. Both checksum and CRC error checking is included in
PC-PLOT-IV. |
| |
|
|
| PC-PLOT-IV includes
a mode which allows you to temporarily exit from the communications manager,
get a PC-DOS command-level prompt ( C> ), and execute either a PC-DOS function
(such as DIR or CHKDSK) or run another program (such as a text |
| editor). Upon completion
of the PC-DOS task, you will re-enter the communications manager of PC-PLOT-IV
where you will see any data which was sent by the host while you were executing
the second task. |
| |
|
|
| Interactive cursor mode
(GIN mode) is implemented in PC-PLOT-IV using either the cursor control
arrows or a mouse pointing device from Mouse Systems (PC Mouse) or the
serial mouse from Microsoft. |
| |
|
|
| PC-PLOT-IV includes
several utility programs which complete the software for a graphics workstation.
HPPLOT is a program that interprets the Tektronix 4010 commands saved in
a disk file of a picture and sends them to a Hewlett Packard pen |
| plotter
that uses the Hewlett-Packard Graphics Language (HP-GL). The picture files
saved by PC-PLOT-IV are the full resolution data sent by the host computer,
not the image presented on the screen of your computer so that when the
HPPLOT utility is used the resulting plot is a full 1024 x 768 resolution.
The standard version of HPPLOT furnished as a part of PC-PLOT-IV supports
only monochrome graphs (one pen). |
| |
|
|
|
|
|
|
|
|
|
|
|
| PC-PLOT-IV
includes built-in programs to dump a graphics image to a dot matrix printer
or Hewlett-Packard LaserJet printer. |
| |
|
|
|
|
|
|
|
|
|
|
|
| PC-PLOT-IV
is NOT !! copy protected for your convenience. We will not restrict
the way in which use use PC-PLOT-IV legally. It may be copied for backup
purposes onto floppy disks or on to a fixed disk in a PC-XT or PC-AT (see
complete text on copying limitations in the copyright notice on the second
page of the manual). |

|
|
|
|
|
|
|
| |
|
|
|
|
|
|
|
|
|
|
|
| You will
need the following hardware and software to operate PC-PLOT-IV in your
computer system: |
| |
|
|
|
|
|
|
|
|
|
|
|
| |
*
An IBM PC, I disk drive, 256k memory |
|
|
| |
*
A Asynchronous Communications Adapter |
|
| |
*
A suitable graphics board |
|
|
|
|
|
|
| |
*
A dot matrix printer (optional) |
|
|
|
|
| |
*
A pen plotter (optional) |
|
|
|
|
|
|
|
| |
*
IBM PC DOS Version 2.0 or later |

Tek 4010 |
|
|
|
|
|
|
|
|
|
|
| |
|
|
|
|
|
|
|
|
|
|
|
| The Tektronix
4010 emulation is complete. Graphics input mode is supported using a small
tracking cross rather than a full-screen cursor. The only feature which
is not supported is 'margin 1'. A real Tek 4010 terminal wraps text from
the bottom of the screen to the top center of the screen. PC-PLOT-IV wraps
text from the bottom to the top left margin. |
| |
|
|
|
|
|
|
|
|
|
|
|
| |
Tek 4014 |
|
|
|
|
|
|
|
|
|
|
| |
|
|
|
|
|
|
|
|
|
|
|
| The Tektronix
4014 emulation is as complete as possible for the graphics hardware available.
Since there are only 200 or 350 lines on the screen, the smallest character
sizes which can be drawn are the 8 x 8 characters which are the normal
size. The 4014 commands for variable text size are parsed but ignored. |
| |
|
|
|
|
|
|
|
|
|
|
|
| |
Tek 4027 |
|
|
|
|
|
|
|
|
|
|
| |
|
|
|
|
|
|
|
|
|
|
|
| The Tektronix
4027 emulation includes only the graphics and cursor control options. Functions
which relate to setting the communications channel and other non-graphics
functions are not supported. All options in the Polygon, Circle, color
map, and color mix commands are not included. |
| |
|
|
|
|
|
|
|
|
|
|
|
| |
Tek
4105 (optional) |
|
|
|
|
|
|
|
|
| |
|
|
|
|
|
|
|
|
|
|
|
| The Tektronix
4105 emulation is only partial. It includes all the necessary drawing,
text size, line type, and color select commands to be a functional 4105
emulation. Since graphics boards for the IBM PC have only a single memory
plane, the scrolling dialog region is simulated. The bottom 32 scan
lines are reserved for a 3 or 4 line dialog area which scrolls. |

|
|
|
|
|
|
|
| |
|
|
All cursor control and
edit functions are supported 8 bit control modes are not supported |

|
|
|
|
|
| The VT-640 emulation
is only partial. Since there are no available graphics boards for the IBM
PC which have independent graphics and character screen memories, true
scrolling of text over graphics is not supported. |
