Hi,
received my two 232+OLEDs today, thanks!
Attempting to use it for inbound telnet to the old "Simplex BBS" software, I'm getting pretty far, but when nc'ing (netcat - so not telnet) to the BBS and then ctrl-C-ing netcat - which closes the connection and presumably sends TCP RST and all that - I see the BBS receiving a "NO CARRIER" string from the modem, and then the software goes into a loop where it says carrier was dropped, and then attempts to reset the modem - which again brings it to the "carrier was dropped" message, ad infinitum.
If I allow the BBS software itself to do the disconnect (timeout or whatnot), it manages just fine.
The OLED reads "Ready" when this happens.
I've tried all variants of AT&Dx, but haven't played much with other settings.
I find it hard to debug what's going on here, so I'm humbly(?) asking for some ideas of what to look for, and how. It could be a hardware (serial ports?), driver (OS/2 1.3 + Digi ClassicBoard serial card driver), software (Simplex for OS/2) or config problem.. I just don't know where to look.
Thanks again,
