C2509 8k mem C2500-I-L v12.0(14) with dumb terminals attached via octal & cat5 cabling. Problem is some terminals cannot connect to the host when logging on, blank screen, other times users are in the system, then 'closed by foreign host' message then blank screen. Async config is:
line 3 8
exec-timeout 0 0
no activation-character
session-limit 1
no vacant-message
autocommand telnet synsys
no history
no editing
transport preferred telnet
transport input all
transport output telnet
escape-character NONE
stopbits 1
speed 19200
flowcontrol software
To enable the terminals, config mode and enter 'no modem inout' again, then they can log back into the system. Why do I need to keep putting in this command? This doesn't happen with all terminals, and no obvious pattern is emerging. Has anyone any ideas? I'm a bit stumped on this one. Cheers!
