I just upgraded from 4.0.3 to 4.1.1, and now the terminal hanging off the first serial port on my SPARC Station 1 doesn't respond. I get the console message : getty: /dev/ttya: No such device or address I've tried both ttya and ttyb and double checked my ttytab file. I'm running an untouched GENERIC kernel at the moment. /dev/ttya looks fine : crw-rw-rw- 1 root 12, 0 Feb 11 14:58 /dev/ttya Any suggestions? I heard that this was a vicious problem in old SunOS's in the past. I welcome any help, because I've only been managing unix for a year...

I thank those who responded to my question : >I just upgraded from 4.0.3 to 4.1.1, and now the terminal hanging off the >first serial port on my SPARC Station 1 doesn't respond. I get the >console message : >getty: /dev/ttya: No such device or address I got it working by shrinking the GENERIC kernel (under which the above problem occurred), by cutting out what I didn't need. It worked upon rebooting. Suggested Solutions: 1) 4.0.3 4.1.1 ttytab difference : the 'local/remote' parameter. - I tried it and it didn't help 2) Forgot to re-read the ttytab file (kill -1 1) - Nope, I knew that. 3) Jumper pins 4 to 5 and 6,8 to 20 on the serial connection. - Saved it for the last resort, so I didn't try it. 4) Device driver not configured in kernel (memory problems) - Could be. But it remained untouched between kernels. I am assuming it was a memory (not enough of) problem. I am running a SPARCstation 1 with 16megs. Perhaps the GENERIC kernel was just a bit too much for it? If you're uncomfortable with that answer, so am I . . .
