You'll have to listen on a second COM-port. Of course, you'll have to
connect the Rx-wire of COM1: to Rx-wire of COM2:
Assuming your modem is connected to COM1:, then write a small program
where you set the identical baudrate as used on COM1:, open COM2:, read
the input and print it on a form.
I oftently use a DOS shareware program which listens to *both*
directions, but therefore you'll need a second PC, of course. This leads
to another question: maybe somebody knows something similar under
Windows?
Maybe with some features like
- time stamping
- controlling the control signals too
- archiving and retrieval
- a kind of control language for protocol simulation
- ...
Or do I have to write my own?
