I have a slackware machine and I'd like to have a serial console on it. I have a RJ45 console on my hardware. I can now only get output on the console and cannot give any input back to the device. Login prompt appears but I can't type anything into the console. in
s1:12345:respawn:/sbin/agetty -L ttyS0 38400 vt100
I have the same problem on ubuntu server 14.04.
