Hello. I am currently running ISC UNIX V.3 on an 80386 with a Hayes Smartmodem 1200. The only phone line I have at this time is my voice line. What I would like to do is have my system be able to receive calls at certain times/days. But I also need the system to be able to call out when it has to do its polling for news and mail. The modem is connected to tty01. Any help and information the resident UNIX communication GURU's could give me would be greatly appreciated. Thanks in advance.. -Jo ------------------------------------------------------------------------------- |Joseph E Poplawski (Jo) US Mail: 1621 Jackson Street | | Cinnaminson NJ 08077 | |UUCP:..!rutgers!rochester!moscom!telesci!fantasci!jep | | ..!princeton!telesci!fantasci!jep Phone: +1 609 786-8099 home | | ..!pyrnj!telesci!fantasci!jep | -------------------------------------------------------------------------------

The modem is connected to tty01. Use uugetty (it's in /usr/lib/uucp) for that purpose. An entry in /etc/inittab should look like 01:234:repawn:/usr/lib/uucp/uugetty -r -t15 tty01 1200U where 1200U is an entry of /etc/gettydefs. Uugetty can handle both incoming and outcoming calls. -- -- ###### Jos Vos ###### Internet jos@idca.tds.philips.nl ###### -- ###### ###### UUCP ...!mcvax!philapd!jos ######

Uugetty can handle both > incoming and outcoming calls. I have a number of problems when I try this. The device tty01, as delivered, isn't a modem control port, and therefore doesn't work right for dial in. Uugetty dies as the modem answers the call, causing the modem to immediately drop the line again (when using the modem-control port). If a process opens either the modem control device, or the no wait device while someone is dialed in through the modem control device, the line is dropped. (Try to determine the baud rate of the incoming call using 'stty < /dev/tty01'.) NO, I cannot re-wire, nor re-configure my modem. The modem is an internal modem, so can't be re-wired. The current configuration works perfectly when the modem is used for either incoming or outgoing calls seperately. If only we were using Microport's version, we could dispense with uugetty and one-way modems. They use a scheme in which an open on the modem control device by getty (which is still blocked because there is no DCD signal) is prevented from completing, by the device driver, while the no wait device is open, and vice-versa (except that when the modem control port is in use, no wait device opens fail, not block). [ This is how it was described to me, subject to my interpretation as to how the ideal situation should be. ] -- Greg Woods.
