[parisc-linux] Help! can't get serial console on 715/75

[morrison@southwind.net]

I recently acquired several HP 700 series boxes, and am not able to 
get into a serial console on a 715/75.  I did not get any monitors with 
them.  I have been able to get a serial console up on a 715/100, and 
on a 735/125, so the serial setup is known to work, but the 715/75 
boxes simply will not respond.  I have disconnected the graphics 
card, with no change.  I do have HIL keyboards, but have not been 
able to set the console to rs232 working blind.  Suspecting secure 
mode was on, I disconnected all drives and attempted to set secure 
off blind, to no avail.

Any help appreciated, additional info available if it will help
