Oh, ok. Now I'm with you. Sure, for this you don't want mgetty. Just use the regular getty that's already on the system. Here's what you do. First edit /etc/inittab to get init to run a getty on your chosen serial port (I'll assume for purposes of exposition you want to use the first serial port, /dev/ttyS0). I'll also assume you want to run the port at 38400bps. Add the following line to /etc/inittab:
T0:23:respawn:/sbin/getty -L ttyS0 38400 vt100 Now to get init running this do 'kill -HUP 1' (init is always the first process in linux and so will always have the pid 1, the HUP signal tells init to reread /etc/inittab and act accordingly for any changes). Now the getty should be running. On your laptop you'll want to install a terminal program. I prefer seyon (which is an X app) or minicom (curses app). Hook up your null-modem (Rx and Tx are swapped) serial cable, run your terminal program, set the bps to 38400 and you should be in business. You should get a login prompt.
