grub serial port option problems

[Bill Huey (hui)]

Hello,

I'm having problems trying to get the menu to come up in grub via the
serial port. Was there some changes that disabled that ? This under
the AMD64 architecture.

I'm using "terminal --timeout=0 serial console" and I believe that should
sufficient to get it to response to a serial port character to bring up
a menu but it seems to ignore it. However it does print the message
prompting for a key press to continue.

What am I doing wrong and what kind of problems
