I just switched over to a 3b1 from my old UNIX PC, and in the process I installed the 3.51 foundation set and the 3.51m upgrade (FIX DISK 2.0). For some reason, my external modem is now exhibitting a strange behavior that wasn't there before. With the uugetty running on the tty (tty002), when I try to place an outgoing call, the modem (a Hayes) sends an OK\r Result Code, and the uugetty sees this and sends return back to the modem, which echoes it back...The send and receive lights on the modem end up turning on constantly, and if I do a direct connect to the modem via cu, I see a continual stream of 'OK's followed by two carriage returns. Now, this didn't used to happen before, and if I kill the uugetty (remove it from the inittab) the problem goes away. The question is: Why isn't the uugetty being put to sleep by UUCP and why is it playing this game of tag with the modem? I noticed in the FIX DISK that a number of potential culprits were updated: setgetty, getty, login, init. I'm using the suggested setup for Hayes 2400 Smartmodems which was posted to the net about six months ago (CLOCAL is disabled, etc). It worked fine before, but now I'm getting this strange echo problem. Any ideas out there? -- Marc Weinstein {simon,royko,tellab5}!linac!fithp!mhw Elmhurst, IL -or- {internet host}!linac.fnal.gov!fithp!mhw
