Quoting from section 11.1 of the ckuker.bwr file that comes with C-Kermit
5A(190), "C-Kermit as an External Protocol", which applies to "pmcomm" but
probably is also relevant to this question (I'd appreciate feedback on
this so I can update the documentation):
"pcomm" is a general-purpose terminal program that provides file transfer
capabilities itself (X- and YMODEM variations) and the ability to call on
external programs to do file transfers (ZMODEM and Kermit, for example).
You can tell pcomm the command to send or receive a file with an external
protocol:
send receive
ZMODEM sz <filename> rz
Kermit kermit -s <filename> kermit -r
pcomm runs external programs for file transfer by making stdin and stdout
point to the modem port, and then exec-ing "/bin/sh -c xxx" (where xxx is
the appropriate command). However, C-Kermit does not treat stdin and
stdout as the communication device unless you instruct it:
send receive
Kermit kermit -l 0 -s <filename> kermit -l 0 -r
The "-l 0" option means to use file descriptor 0 for the communication device.
In general, any program can pass any open file descriptor to C-Kermit for the
communication device in the "-l" command-line option.
