You should probably post on hardware or OS forum. You startup should have some code that would listen for serial 
connection and start the shell when it is plugged in

An update:

in both QNX 6.3 and 6.5 there is output available, but input is not possible.

If I do >cat /dev/ser2 in a telnet session, then I can see the typed characters both in hyperterminal and in the telnet 
window.

Any ideas?
