This suggests that data is not arriving from the external device, and that
would explain why it's not being logged.
Leaving aside the recording aspect for the moment, is there any way you can
view the data from the device on the MS-DOS Kermit CONNECT screen? If not,
then evidently some adjustments are necessary to Kermit's communication
settings (speed, flow control, parity, etc), or to the cable. The wiring of
the cable depends on the characteristics of the device -- is it a DCE (like
a modem) or a DTE (like a computer)? Does it use the RTS, CTS, DTR, and CD
leads for anything, and if so, what?
Once you can view the data on the screen, then your script needs to do
whatever you did by hand -- use OUTPUT commands to send what you would type,
etc.
