I've got a curious problem that seems to be immune to solution: There is a customer of ours that desires a leased line for a remote terminal. Never mind the cost of leased vs. dialed, etc. I just can't get the damn thing to stay connected or to display a 'login:'! The gettydef on the line is the 'm' entry (should look local), the tty is /dev/tty1a (note the lower case 'a'). The modems are Hayes 9600 V.32's and their front panels indicate a modem<->modem connection. The connection is using a 2 wire leased line. I'm at a loss. The problem appears to be in the modem<->system connection - I'm flying someone out today with smart cables to check (did I mention the site is about 500 miles away?). Any ideas? (Only *useful* ideas need apply ;-) -- Russ Kepler - Basis Int'l SNAIL: 5901 Jefferson NE, Albuquerque, NM 87109 UUCP: bbx.basis.com!russ PHONE: 505-345-5232

You might have a BAD leased line. I have a site that uses 3 terminal and a printer about 15 miles from the host Xenix box. They had a 2 port Mux and some 2400bps modems trying to attempt 9600 via compression. (Whoever set that up should have been shot). I put in a good mux, and we went to Trailblazers. Things got better, but still there were times that it wouldn't connect, and sometimes disconnect several times a day. I heard noise on the line and called telco. Both companies (Bell & United - two different exchanges replaced some channel boards). Still somedays good. Somedays bad. One day (after an overnight rain storm) it wouldn't come up until about noon. Telco took a thorougly dead roach from the connectors. But the average disconnect was about 6 times per day. I FINALLY convinced them to put the TB's in a dial up mode. Have had ONE disconnect in six weeks with dialup, opposed to 6 per day per leased line. I have come to the conclusion that the only thing that a leased line gets you is a bigger phone bill. -- Bill Vermillion - UUCP: uunet!tarpit!bilver!bill : bill@bilver.UUCP
