Any vendors 56K modem should work with the PM3 today. However it will only
connect in V.34 speeds and below. I do know the Hayes modems require
AT+ms=11,0,300,33600 which disables 56K mode, to successfully connect with
the existing PM3 modems. After the PM3 K56flex modem cards ship, any
Rockwell or Lucent-based modem should connect in K56flex mode. A list of
these interoperable K56flex modems can be found at www.rockwell.com or
www.lucent.com
