Before proceeding... There are SO MANY things to rule out, that
it's better to just start from scratch.
. Are you really using a true null modem cable?
. Did you tell BOTH C-Kermits to "set line /dev/ttya"?
. Did you tell BOTH C-Kermits to "set speed 9600" and "set flow rts/cts"?
. Are you sure?
. Might there be a getty running on any of the ports involved?
The best way to debug this type of connection is to put both Kermit
programs in CONNECT mode and type stuff. Whatever you type on computer A
should show up on computer B's screen, and vice versa. If not, then
the most likely problems are listed above.
RTS/CTS is not necessarily well implemented in all version of SunOS.
Does "set flow none" make a difference?
Once you get CONNECT mode working, file transfer should also work.
If you have any more problems, send details to kermit@columbia.edu.
