We are using MSCP controllers that look like uda-50's to our unix.  In the
config I call 'em uda0 and uda1,  not kda (never even heard of a kda...).

His config file still could be wrong.  I know enough about the subject to
know that it may be possible.

It may matter to his flavor of unix.  Mine (mt Xinu 4.3) expects the config
just as I originally posted it.  

I hope this fellow posts the fix as soon as he gets it,  I'd be interested
in finding out what the problem was.
