Barry, I never used a loopbak device, I did attach a modem and send to it an ATIx command which makes the modem answer back with some internal data/status.
I was even able to print to a serial printer from linux (an old mandrake). That said, tp_xxx is just a prof of concept and it was not finished nor polished because the project that should have used it never saw the light. So, I'd look at the C code, is very simple, maybe you can put some printf() there to see what happens at the low level. I'd also try a tp_recv( 1, 1 ) // see second one, which is num of chars to wait. Also, tp_recv() calls fetchchars() which calls p_ReadPort() which is the function that does the real work and is written in C. Hope this helps you in some way. Maurilio.
