multi-port serial devices

[Jim Pazarena]

just purchased Specialix SX modular high speed serial solution

Specialix has changed their name (bought out by perhaps) to Perle.

The FreeDSD 5.4 hardware compatibility list indicates 
"Specialix SI/XIO/SX" multiport serial cards, are supports (si(4) driver)

however a compile of the kernel with  "device si" doesn't even
discover the card. The supplied DOS utility to probe the device works
as expected.

Can anyone offer a suggestion.

Thanks, Jim
