Please respond if you have any suggestions. I am trying to connect two FreeBSD machines via serial ports. I was trying to use PPP but someone suggested running getty on one and tip'ing from the other to troubleshoot. I have successfully run getty on the one, have a null modem between the two serial ports. When the systems boot they both see a sio1. So far so good. When I tip on the other machine to /dev/ttyd1 nothing happens. I get a newline from hitting enter and then nothing. I can CTRL-C out of it. If I tip to /dev/cuaa1 then the console locks up completely. I have to switch to another v. console and kill -KILL the process to get the console back. What does this mean? What should I try next. I thought this should be easier but I am tearing my hair out on this one. BTW the serial cable is a null modem, DB25 female - DB25 female from Radio Shack. I have tried other cables including a serial cable with a null modem adaptor but all with no luck. Any help would be much appreciated.
