Where are my serial ports?

[Jeff Adams <jadams@hoovers.com>]

Greetings,

I recently acquired an Ultra 5, on which I'm running Testing. Works 
great for everything I've asked of it so far. Thanks to everyone putting 
this distribution together.

I'm now attempting to utilize the 9 pin serial port, but as far as I can 
tell, the OS doesn't seem to see it, and I'm not sure how to tell if the 
machine sees them. I've tried cat'ing all the ttySx devices, but all 
claim something to the effect of "no such device" (don't have the exact 
message at the moment, Sorry). However, I've used this technique 
succesfully on my x86 machines, and even on an SS20 (also running Debian 
:), so I'm somewhat befuddled as to what's going on.

FWIW, I've compiled my own kernel from  Linus' tree, but I don't recall 
seeing an option to configure serial devices, as I'm used to seeing in 
the x86 kernels.

I'm hoping some gentle soul can provide some enlightenment as to which 
devices the serial ports on an Ultra 5 usually reside at, anything I 
need to check at the boot prom level to ensure they are enabled, or any 
other bits of information that will help me find my serial ports.

Thanks a bunch,

- Jeff
