Subject: MS-KERMIT 3.14 hanging on idle TCP/IP connection?
Date: 3 Sep 1995 20:24:41 GMT
Organization: Columbia University

PROBLEM #1: If I leave MS-DOS machine running Kermit idle for
(let us say) 15 minutes, then the terminal stops showing
input and output.
PROBLEM #2: After reaching the state described in Problem #1, it
is no longer possible to start other TCP/IP sessions.
PROBLEM #3: Upon exiting kermit, the PC machine freezes up,
requiring a Control-Alt-Del, and sometimes a power-down. In general,
it seems that the problem reappears if one does NOT use a power-down.
I have read the kermit.hlp and kermit.bwr but remain unenlightened.
BACKGROUND:
1. I have been using MS-KERMIT 3.14pl9 to connect from MS-DOS
machines (486 w/ MS-DOS 6.22 and a XT w/MS-DOS 5.0 and ANSI.SYS) to a
Linux machine. All the involved machines have 3Com ethernet cards,
and all three are located on a TCP/IP ethernet with about one meter
distance between them.
2. I am positive that the problem is not the Kermit has dropped the
connection. Because the machines are setting next to each other, I
can look at the Linux machine and see what program is being run on the
"hung" machine running Kermit. I can also "logout", etc.
3. I have tried SET TERM RESET, Alt-=, set term none, and anything
else I could find in kermit.hlp that seemed relevant, but this
did not help.
4. As mentioned above, when exiting, the PC freezes. As suggested
in KERMIT.BWR, it is possible to push to DOS, etc., while the
session is still running, but hangup and exit result in the PC crash.
I can provide more information if the preceding was not sufficient.
Thanks for any advice/help/suggestions.
Cheers,
Seth Chaiklin
