:
: receiving, from remote to local unix, works fine.
: there i have no problems.
: again - transmitting, from unix to remote, does not work.
: it doesn't start the sx program.
:
Both sending and receiving work fine:
$ whereis sx
sx: /usr/local/bin/sx
$ ls -l /usr/local/bin/sx
-rwxr-xr-x 1 root 65536 Nov 18 1990 /usr/local/bin/sx
$ kermit
(C-Kermit 6.0 banner and greeting)
C-Kermit> set proto xmodem
C-Kermit> show proto
Protocol: XMODEM
Executed by external commands:
SEND command (binary): sx %s
SEND command (text): sx -a %s
RECEIVE command (binary): rx %s
RECEIVE command (text): rx %s
Autoreceive command (binary): rx %s
Autoreceive command (text): rx %s
C-Kermit> send x.x
Sending x.x, 1 XMODEM blocks. Give your local XMODEM receive command now.
(and the file is transferred).
If C-Kermit can't start an external program, that's because it can't find it
(e.g. because the program is not in your PATH), or it lacks permission, or
some similar impediment. If it *can* start the external protocol program,
but it doesn't work, then we have an additional list of possible problems:
program is not redirectable, connection is not sufficiently transparent for
this protocol, program doesn't work, etc.
If you have further trouble, please send email to kermit-support@columbia.edu,
rather than continuing the discussion here, since we have passed the point
where the information in this thread is of general interest.
