I believe > the Hayes Smartmodem 9600 has this property. The "Hayes Smartmodem 9600" is a V.32 modem. I'm sure you're referring to the "V-series Smartmodem 9600", which uses a proprietary half-duplex ping-pong modulation scheme. The "V-series ULTRA Smartmodem 9600" (Ultra 96) supports both V.32 and the proprietary scheme. -- Toby Nixon, Principal Engineer | Voice +1-404-840-9200 Telex 151243420 Hayes Microcomputer Products Inc. | Fax +1-404-447-0178 CIS 70271,404 P.O.
