Ummm, with reservations, perhaps. Aren't fax modems (nearly) half-duplex? That is, they transmit at full 9600 bps in one direction, but only receive low-bandwidth data in return. Basically like the old Bell 202 modems, back when 1200 bps was pushing the envelope. Dave dbell@cup.portal.com

And a V.32 modem can operate in full duplex at 9600 bps on standard switched telephone lines. These modems became widely available after 1986, many BBSes provide support for them and more and more people I correspond with have them. BYTE Magazine (November 1990) had an article on modem standards. ...bag bradley.grigor#canremote.uucp Newmarket, Ontario, Canada PCRelay public key: 7596 12-24-90 at 12:34am --- ~ DeLuxe}ab #4613 ~ Frugality: who can afford it? -- Canada Remote Systems.
