[CentOS] is it possible to login to a switch via RS232 / serial port from the shell?

That should work, but I usually use kermit which has a lot more options 
and is scriptable.

With kermit, try:

set line /dev/ttyS0
set carrier off   (just in case the device doesn't raise CD)
connect

then it is control-] followed by 'c' to get back to kermit.
