My remote host is a laptop with only one sio port. So if it would be possible with a single serial connection I'd appreciate it. I have played a little with remotechat but with strange results. If I set remotechat before `target remote /dev/cuaa0' the latter fails. If I set remotechat after `target remote' but before continuing ctl-alt-esc on the target host doesn't work anymore. Only garbage appears in the remote gdb. Also ctl-c in gdb doesn't achieve anything. Only after three ctl-cs I can detach gdb. I have now also added option ALT_BREAK_TO_DEBUGGER but that doesn't help either nor does the sequence CR~^b in gdb. (I want to interrupt the target host while X is active.) > If the hang is not a system hang, the console break will have an effect. > But if the kernel is so hung that the keyboard doesn't work, the remote > serial console will not do you any better.

I'm just hoping the hang is not a system hang. :-) -Hanspeter To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
