Subject:   serial console broken after 4.3-RELEASE?
Message-ID:  <20010729130746.A44997@mighty.grot.org>

I have a machine that was cvsupp'd from 4.0-RELASE to 4-STABLE with the latest
cvsup on May 21st:

   FreeBSD 4.3-STABLE #0: Mon May 21 09:22:22 PDT 2001

Till that cvsup, the serial console on sio0 was working well. Neither the
boot-up redirection (-h) nor the tty on the serial port works after that
cvsup. I'm seeing similar behaviour on another machine cvsupp'd on that date.

I have the following in my kernel:

  device          sio0    at isa? port IO_COM1 flags 0x10 irq 4

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/serialconsole-setup.html
says it should be:

  device sio0 at isa? port "IO_COM1" tty flags 0x10 irq 4

however the "tty" bit isn't in LINT nor documented anywhere, plus config
doesn't like it.

Furthermore, I have the following in /etc/ttys (unchanged from 4.0-RELEASE):
 
  ttyd0   "/usr/libexec/getty std.9600"   vt100   on secure

and I see that the getty is running on bootup:

  790  ??  I      0:00.01 /usr/libexec/getty std.9600 ttyd0

however connecting to COM0 on the machine no longer produces a login prompt.

Hints? Ideas? what changed?

Adi
