This is 5.2/i386 on an IBM Thinkpad T40. As this laptop does not have a serial port, I bought me this USB-to-serial gizmo:
uplcom0 at uhub2 port 2 "Prolific Technology Inc. USB 2.0 To COM Device" rev 1.10/3.00 addr 2 ucom0 at uplcom0 I am trying to an ALIX running current/i386. >From a machine with a serial port, I connect as cu -l /dev/cua00 -38400 and it works fine. The baudrate is indeed 38400; it is set so on the ALIX, and /etc/boot/conf says stty com0 38400 set tty com0 Now from this Thinkpad, I try to connect with cu -l /dev/cuaU0 -38400 That say 'Connected', but nothing else happens. I can see a garbled login screen such as kXKMr/i386 (gw.stare.cz) (tty00) login: -i I usually see something like that with a wrong baudrate. There is no reaction to nothing. All I can do is ~. to disconnect. What kind of problem is this? Can my ucom do 38400? How do I find out? Would it make sense to try other baudrates (on both the ALIX and my end, obviously)? Is anybody using an USB-to-serial connection to an ALIX?
