Over in the comp.sys.ibm.pc.soundcard group there have been a couple of brief mentions of the new "Windsurfer" card from IBM. It apparently incorporates a couple of DSP chips, a 14.4K modem, a soundblaster emulator, general midi, kitchen sink, etc :-). I don't know if these DSP chips will be user programmable or not, but if so, this sounds like the one board you need to build your very own secure phone. The 14.4K modem for sending the data, the DSP chips for audio compression, and the sound board for digitizing speach and playing it back. Throw in a little private key exchange via RSA or equivalent at the start of the connection, and use triple DES or IDEA on the data (of course, the person at the other end needs the same setup). Does anyone have any more details on this board (like, will it be user programmable, and will the specs be available for less than your firstborn child :-)? -- ====================================================================== domain: tahorsley@csd.harris.com USMail: Tom Horsley +=============================================+511 Kingbird Circle Don't have awk?
