okay, i got serial output to a file to work, but can't seem to make an
interactive serial connection to xen. here's what i did:
1) compiled xen with env var 'debugger' set to 'y'
2) added 'com1=9600,8n1' to xen boot line
3) set virtual com1 in vmware to named pipe ("this end is client"/"other
end is app") called /tmp/xen-com1.
4) ran socat on host machine:
socat UNIX-LISTEN:/tmp/xen-com1,unlink-early,fork pty,link=/tmp/com1
to convert pipe to pty.
(both the pipe and the pty appear in /tmp)
5) booted xen in vmware (at some point, it stops sending output to vmware
-- a good sign)
6) connected to /tmp/com1 with kermit:
kermit -b 9600 -l /tmp/com1
7) typed ^A^A^A then 'h', but got no response.
what did i miss?
thanks,
