New Firmware Upgrade
For USR Courier 2400
Kurt Reisler - SYSOP

Once again, US Robotics has an upgrade to the PROM-based
firmware of our USR Courier 2400 modems. The latest PROM
release has a product code of 243. To determine the product
code of the PROM in your modem, startup your favorite
communications program, and type the command "ATI0" and hit
the return key. If your modem returns 243 as the 3 digit
product code, then you have the latest release of the
firmware. If anything lower is returned, you should call US
Robotics immediately and request a firmware upgrade. They
are doing this on an exchange basis, as they did with the
upgrade from 241 to 242.
To get your PROM upgraded, call US Robotics at 800-DIALUSR,
and ask for Technical Support. Tell them that you need the
PROM upgrade and they will take care of it for you.
Replacing the PROM is a simple proceedure. Pop the old one
out, and gently insert the new one. That should be all
there is to it.
From what I understand, the new firmware corrects the
"streaming" problem that some of us were having when we
called other USR Courier 2400 baud modems. The streaming
problem was characterized by the modems connecting, and one
or the other generating a continual stream of garbage. The
only way to break the connection was either to drop DTR, or
to physically turn off the modem. Not a major problem
during a manual call, but mine would up attached to a long-
distance FIDO for 2.5 hours during FIDONET time (OUCH, my
aching phone bill!). The new proms also correct a
connection problem with Ventel 2400 baud modems.
