B balanga Aug 22, 2018 #1 I've just hooked up a ThinkPad T42 to a docking station which has an RS232 port. How do I tell if FreeBSD (11.2) recognises it? Presumably the existance of some particular file in /dev/ would tell me. Running grep uart /var/run/dmesg.boot did not show anything.

OP B balanga Aug 22, 2018 Thread Starter #3 Datapanic said: Is it enabled in the BIOS? Click to expand... I guess so since I booted up Arch Linux and was able to use the port which was identified as /dev/ttyS0. Having said that I've just checked the BIOS and it was marked as disabled so I don't understand how Linux was able to use it.... Just noticed on rebooting after enabling it, I now have a /dev/ttyu0 so I guess that must be it.
