The only change was to add the modem setup for sending pages:

	PagerSetupCmd:	AT&N2&K0&M0

We aren't using the fax server yet.  Just alpha-numetic paging.  No, I've 
used the
usr-rts configuration file "out-of-the-box" for the Sportster and the mt-1432 
for the
MultiTech's.  The only additions were the PagerSetupCmd line.

BTW: for the MT2834BR "PagerSetupCmd: AT$MB1200&E0&E14" seems to work.

IMHO, the terminal server is not introducing anything different that what the 
standard
/dev/tty[ab] provides.  We're using Digi PortServerII's and their RealPort 
drivers.  We
use them with our own software to control the surveillance cameras and 
changeable
message signs all up and down the freeways in Atlanta.  Work fine.  Besides, 
I can
force the server to use a specific modem (sendpage -h cua_a003@faxserver ...) 
and
the page goes through.

I think the problem is with the scheduler or something else in the server, 
not the
'pagesend' program or modem config.  Can someone explain how the server
decides when, and how many, pagesend jobs run?  Is that too complicated to
discuss here?

Thanks in advance,
