I am able to use cu and tip with this device and modem without noticeable problems. Just to be sure, I tried again. I used "cu -p port4" where port4 is setup as a direct connect to the modem. I typed 'AT' and 'ATZ' and got back 'OK' in both cases. I then exitted cu, and confirmed that the lock file had been removed. I then tried 'ppp myisp' and 'show modem' to confirm that everything was setup to talk to the correct device (/dev/cuaa1) and the modem. (BTW, outq showed 0 at this point). I then typed 'term' and typed 'AT' and ATZ' with no response. After typing '~.' to return to the ppp prompt, I typed 'show modem' again. Outq showed '7' now, which implies (to me) that no characters were sent out the device port. It seems that nothing is getting to the modem... -- Stephen At 08:35 PM 12/30/95 -0800, Gary Kline wrote: >According to Stephen Couchman: >> >> Barry, >> >> I'm pleased to see that you figured your problem out.
