A friend and I recently struggled to get my new 33.6 Dynalink modem
talking to his USR Sportster 14.4. We both were using the standard USR
init string for the USR Sportster (AT&F...AT&K0&M0) to no avail.
Technical support and all data we could find led us to dead ends.
However, after some wild guesses, we found that by adding &B1 (Fixed
Serial Port Rate) to the end of the string, ICR2 connected and worked
well. Hope this may save someone out there some pain and suffering.
CIAO.
