Hey guys. The problem is myself, of course. I'm trying to communicate bi-directionally through ttyS0. I have tried agetty, but I get messages like 'pam: Invalid user"<server output>"'
By using:
stty 115200
cat ttyS0
I can see all the server output, up until it waits for input from me. This is where the rut lies, using this method is one-way communication. By using agetty or mgetty, it seems like the programs are creating a login prompt with the serial port. Upon receiving data from the server, these programs quit.
The goal here is to have two-way communication without any login, somewhat a simple direct terminal to the serial port.
you should add the agetty commands to /etc/inittab to make it respawn, i set this up recently and didn't get anything actually functional till i had it in there: "s0:2345:respawn:/sbin/agetty -L 115200 ttyS0 vt100"
