Hello all, I have a Supermicrio P4SC8 motherboard and I want to receive its BIOS console redirect output on another FreeBSD box. The motherboard is checking for *something* to see if a serial terminal is attached, and rejects the link. I tried 'tip com1' with an /etc/remote setup of com1:dv=/dev/cuaa0:br#115200:pa=none: and ports/comms/kermit with set line /dev/cuaa0 set speed 115200 set carrier-watch off connect and in both cases, the motherboard times out and abandons the redirection. On the other hand, when I use MS Windows' HyperTerminal, it works. Interestingly, after the redirection starts (on HypterTerminal), I can pullout the serial cable from this Windows box and attach it to the FreeBSD box running a tip session, and now the output is recieved by the FreeBSD box, and I can tweek the BIOS setup as much as I like. So, I assume the ususal communication parameters are OK, but there is some signal setup that is missing here, that the Supermicro M/B is looking for. I'm sure there are plenty of people here running such a setup. So, could someone enlighten me where to tweek? I've tried 4.10-stable and 5.2.1-RELEASE if that matters. -- Hiroharu Tamaru
