Hi
 
I'm trying very hard to identify the tty on my HP-9000/E45 on which the
system console is attached
I've noticed that when running HP/UX on this box, it auto-detects the
system console, which is btw connected through a MUX.
Is there anyway to detect in a similar manner? Or can some debugging be
turned on to identify it?
I've tried the console=ttyS0 but just doesn't help anything. also tried
with ttys0 tty console
 
Any suggestions would be very happily accepted
 
Regards,
 
William Carlsson

Hello,

this machine is not supported under linux yet.

But I wrote a driver half'n year ago, using the PDC console (ROM)
in Linux. You have to activate the PDC console by kernel compilation
(character device driver, non-standard drivers), and you have to 
create a device /dev/ttyB0 (see HELP button at configuration).

The kernel line parameter, add `console=ttyB0', then the box can
boot as "diskless server", as the MUX (except the ROM PDC console),
the SCSI and the parallel port is not working.

But I will start on a E55 to write drivers (I will start, but I
cannot speak about results...).

BTW: the console port is on port 0 on my MUX ! If the E45 really
can do an autodetection here in the boot monitor (PDC), then this
also works under Linux, but I cannot imagine....
