I'm making progress on getting a simple dialin server going, but am still
having modem problems. The symptom is I can only seem to get data to go
one way. My setup is:
has modem attached to /dev/tty00 (magma 4P card)
has modem attached to /dev/ttya (built in serial)
I use tip on both computers to attach to the modem. Then I dial from
sparc_1 to sparc_0. The modem answers, I get connect messages on both
machines. I can type on sparc_1 and see the text on sparc_0, however when
I type on sparc_0, nothing shows up on sparc_1. Substitution of sparc_1
and tip for a windows PC and hyperterm gives the same symptoms.
I must be getting _some_ communication between sparc_0 and its modem
because I can interact with the modem, see result codes, etc.
I don't think anything is wrong with sparc_1 or the PC because I can dial
in to someone elses service.
I'm at a loss as how to proceed with debugging. 'stty -f /dev/tty00' on
sparc_0 shows identical settings to sparc_1. I've tried various AT
commands to sparc_0's modem to enable/disable XON/XOFF RTS/CTS, etc with
Thanks for any suggestions
