Hey guys!  Look what they're getting around to considering for IBM's!  :-)

Good idea!

You may be interested in the 'soft modem' approach, recently announced by
Digicom Systems Inc. Essentially you replace the ROM on the DSP with RAM
and download the DSP software from your computer. If you would like to
have a modem, you would download the V.32bis data pump algorithms.

At present, there is a Soft Modem(tm) development kit available from     
Digicom, mainly for use by other modem manufacturers. I might write a
little info file on this, if there is sufficient interest.

The kit is based on the Analog Devices 2101 series of DSPs, which are quite
powerful and are available also in low cost or low power versions. Analog 
Devices has a solid track record in signal computing and AD/DAs.
