If this always happens at the same place, then my guess would be it is
Compuserve hanging up on your call, but maybe somebody who has a Compuserve
shell account could comment more intelligently.
: 2) How do I code my kermit script to recognize the fact that "NO

: there a way to avoid this problem?
:
You should not have to do anything special in your script. If you always
put IF FAIL commands after any i/o commands (like INPUT or OUTPUT), it
this should catch the disconnection. SET CARRIER-WATCH should be left at
its default setting (in other words, SET CARRIER-WATCH OFF should not be
used). The SET MODEM command should precede the SET LINE command, etc.
All of this is documented in the manual.
