The zmodem/kermit issue

When Kerberized telnetd was installed on the Athena dialups, users of zmodem complained that uploads of files to Athena, using rz from the sipb locker, were failing. A workaround was given - type "rlogin athena" at the pasta prompt instead of just "athena". Then zmodem uploads worked again.

Requiring this workaround for zmodem means load on OLC. Encouraging people to use kermit should mean we support it better than we do now.

Here's a chronology of related email:

Oliver calls for reexamination of not supporting zmodem, citing Ted suggests trying an alpha version of the Mac client that purports to be better.
Mid-August, 1994
With the term about to begin, everybody got busy doing other things. Since a workaround existed for zmodem uploads, the issue went low on everybody's priority list, so the conversation stalled.

December 14, 1994
Bruce asks for help on comp.protocols.kerberos, comp.sys.ultrix and comp.sys.aix. No help is offered except for some stabs in the dark from epeisach, none of which work when Bruce tries them.
December 29, 1994
Bruce finds a "zmodem options" dialog box on zterm with a checkbox for "escape ctl chars". When this box is checked, transfers work fine. Burce sends mail about it.
