3-3: What is the recommended modem.inf entry for USR 28.8 modems?
Thanks to Christopher Browne (cbrowne@usr.com) at USR for the
recommended MODEM.INF for various USR modems.
This is the .INF as we have it now. It's been tested on NT 3.1 / 3.5
andWfW 3.11 with great success. I've been able to use all of our
modems from the Courier v.34 down to the Sportster 9600 data/fax.
The MAXCONNECTBPS is set at 38400 so that this file works with most
of the installed base of modems. We only started supporting > 57600
with the Courier V.32t.
The MAXCARRIERBPS is set but any dce-dce rate that is reported at
connect isignored since the port is locked. The first release of
this file was in error since it did not contain the &B1 command
and this caused considerable pain for a few folks. My apologies!
Using ITU-T as our default allows a USR modem to connect with more
than USR modems at higher dce rates. This can be changed runtime by
the user either through the phone number "123-123-1234B0" or by
changing the INF file. I would prefer to see the phone number used
so that the modem stays in a more compatible mode by default.

; * A MAXCONNECTBPS of 38400 allows this to be used by older modems
; such as the HST 14400.
; * Compression is off by default because of the lower DTE-DCE rate.
; * ITU-T standards are on by default to ensure compatibility with
; non-USR modems.
; * X4 is set to ensure compatibility with Sportster modems. Advanced
