We're running a Motorola Delta 3600 box, (System V r3.51), and we want to keep a printer attached to the console for record keeping purposes. Is there any way to keep the system from always changing the tty00 speed to 9500 bps? Right now we're sleeping a task on the console, and renewing it once a day via cron, but this is not really satisfactory. kq -- Kevin D. Quitt Manager, Software Development DeMott Electronics Co.

My apologies for providing incomplete information on my problem. 0. (recap) Motorola Delta 3600 (68030 based) System V r3.51 UNIX. We want to put a 1200 bps printer on the console to keep hard copy of problems. 1. There is no speed jumper on the board (MVME147) 2. The inittab line is: co:234:respawn:/etc/getty console console 3. The gettydefs line is: console# B1200 HUPCL OPOST ONLCR # B1200 SANE #Console Login 1200: #console 4. The mechanism we are using now is the file /etc/rc2.d/S99holdtty00, which is executed automatically when changing to init state 2. (The sleep lasts 24.5 hours). nohup sleep 88200 </dev/tty00 & sleep 5 stty 1200 </dev/tty00 stty 1200 </dev/tty00 date >/dev/tty00 5. The following line is in the cron file root. 0 5 * * * /etc/rc2.d/S99holdtty00 6. It is my understanding that Motorola's version of UNIX considers the console even more magical than most, and will not allow the speed to deviate from 9600 bps unless absolutely forced to. If we do not use the "sleep on it" technique, then the first access to the console is at 1200 bps, but every subsequent one is at 9600. Accesses includes such things as "stty </dev/tty00". 7. My thanks to the people who have responded already. 8. Any other ideas/help from Motorola? kq -- Kevin D. Quitt Manager, Software Development DeMott Electronics Co.
