In my case I'm not able to get the serial console working at all. All I get on my display is some periodic commas and D characters. I have it set for Xon/Xoff flow control. Current FBSD versions appear to enable console operations by default on sio0, (with the "flags 0x10" argument in the kernal config file) so in theory all I should have to do is connect a null-modem cable, run a comm program at 9600,N,8,1 - create a boot.config file with a "-D" or "-h" or "-Dh" in it (or specify it to the boot loader at boot time) and get something. I don't get any output. I'm going to try it on another box and see if it's hardware related. (aside: the Intel L440GX+ server board I'm testing this on has a bunch of embedded serial management features, most of which work on COM2. Among other things, it has a "console redirection" feature which does basically the same thing those $300 boards from www.realweasel.com do - and which Rod Smith so helpfully mentioned in the previous thread. Too bad the Intel implementation is buggy.. :-) -- Philip J.
