I have done some work on the serial terminal support today. It is
still in a prelimiary stage, but works almost perfectly at least in
the grub shell.
Some hints to use the support:
1. Check out the current source code from the CVS, of course.
2. Specify --enable-serial to configure.
3. Run make.
4. Run the grub shell.
5. Initialize a serial device by the new command "serial", like this:
grub> serial --device=/dev/ptypa
See the online help, for more details.
6. Set up your terminal. First, run the new command "terminal" with
the argument "serial" specified:
grub> terminal serial
Then, connect to the tty device by your favorite terminal
emulator. I myself use `cu' in the Taylor UUCP package.
% cu -l /dev/ttypa
7. Push any key to continue.
Have fun,
Okuji
