SCO UNIX error 6, HELP

I have a system here running "SCO UNIX System V/386, Release 3.2" I'm not sure if someone has changed anything, but all of the sudden I get constant scrolling errors...

"*** /etc/getty ttyr006 m (CURRENT TIME/DATE):
Cannot open line ttyr006: No such device or address (error 6)"

this scrolls from ttyr000-ttyr007.

The machine seems to be operating fine otherwise, but when clients connect to it via telnet, it is MUCH slower then ever before... Can anyone help me figure out this error and how to get it to stop

N/M I think I figured out the problem, there was a device attached to accomodate some serial connections and it was disconnected, so I reconnected it and it seems fine now.
