I have a problem with my modem: I have been using it with "enable tty1a" which, as I found out recently, doesn't have modem control and the system doesn't automatically logout if I get disconnected. Well, in order to use "ungetty" (I'm starting to use usenet now and need to dial out on that port) I have to have the enable/disable attached to port tty1A. My problem is this: anytime the modem receives a ring, it displays a system message like this "garbage or loose connection on serial port 0; disabling port" or something like that and then it apparently ungettys the port. My dialout is working fine but now I can't call INTO the system! Any suggestions? Zap Savage (aka Tim Cadell)

Assuming a 2400 Hayes compatible, the command: ATQ1 will tell the modem to not transmit any messages, and will keep the OS from getting confused. There are other causes of this problem, but try this first. It is the simplest.

My dialout is working fine but now I can't call INTO the system! If you are using a modem-card: My experience is that the UART is generating an interrupt on Ring Detect. The fix was to lift the UART pin corresponding to RI (I think we grounded it). Paul Chamberlain Computer Product Engineering, Tandy Corp. {killer | texbell}!cpe!tif
