Hallo Rod!
Whatever change is made must not interfere with applications running on existing
hosts. The use case I originally described is a kind of off-normal situation.
Mostly, the hosts will use the serial port for accepting logins.
Especially as you you describe your case this way, I had so many times
success with this idle method.
In cases you are not able (or not allowed) to modify anything on the
system you can simply use a sleep command for that purpose.
1. Login normal to your board (using a serial tty or pc with emulator)
2. do an "exec nohup sleep 86400" on your Linux device (enter this
command over your serial line)
3. The serial line is now idle and you can connect any other device you
like. It will not interfere with a getty. So you can do an stty to
set the parameter for your serial line (from any remote console or
network login on your linux board).
4. The serial line stays in that usable state until the sleep expires
or you just kill it away. After that the getty reappears and you can
continue to use your system normally (connect tty and login).
... there is no other way witch is less intrusive to your system.
