Hi,
at&c? = 1
at*d? = 1
Contrary to what the documentation for wimodem232 says (doc says at*d defaults to 0, but I guess this is down to hardware revisions), both of these are default values.
If I set at*d=0 (normal polarity), or at&c0 (always connected), the BBS fails to "force modem hangup", and upon ring/answer it says "unable to detect baud rate of connect" and proceeds to (fail to) hang up and re-init. Note that the behaviour is the same in both cases.
Using AT&D0 (default) doesn't make any difference in this scenario; it may make a difference depending on how the BBS handles BBS-initated logouts: The config indicates that it uses DTR to kick people out, and only resorts to the ~~~+++~~~ATH approach if dropping DTR fails.
I've never built/used a serial sniffer before, and while I have been involved in building a serial console "bridge" at a point, I don't think that approach would be useful as any change to DTR/DCD/CTS/RTS/whatever states would not be picked up. Do you have any suggestions for what kind of hardware/software I would need?
