[rescue] CRD-5500 RAID Controller and UART/Monitor

[Brian Dunbar]

I have a CRD-5500 RAID controller, installed in a disk array enclosure.

I want to be able to use the serial port (in the docs called a UART/Monitor 
port) to change the RAID level (it's at RAID0 right now).

Attach a straight modem cable, launch TeraTerm on my laptop, boot the 
enclosure, and the boot info from the array flashes across the terminal 
window.  When the thing is done booting it displays 'press any key for the 
menu' but it refuses to respond to keystrokes or any other input.

If you attach the serial cable and launch TeraTerm AFTER boot, nothing 
displays in the screen.

It also behaves this way with a linux box w/ Minicom.

I'm told this unit worked fine at it's previous office, and they were able 
to access the serial port/monitor with no problems.  I could put in service 
at RAID0 .. the unit works fine.  I'm concerned .. the CRD-5500 forces you 
to use the monitor for anything more complicated than shutdown and a (basic) 
status check.

I'm stumped - not that that's hard to do.  Any ideas?
