I saw the Forval/IMC modem at COMDEX/Fall, and spoke with an engineer
about it. It *doe* sound very interesting, with a number of technological
improvements over PEP, and other modems in general:

    - multicarrier protocol, with full data speed in both directions 
	simultaneously
    - 19200 baud base data rate (on pre-compressed data); interface speeds
	up to 56Kb when the modem is compressing on the fly
    - modem firmware is downloadable. You never have to order a new PROM
	set; just call up their BBS and download a new program. (There
	are certain aspects to this that make me a bit nervous, but if it
	is done properly with proper handling of security/reliability
	issues, it sounds like a really Good Thing...)

I hadn't heard of Forval/IMC before; I'm glad to hear that they are more
thann just an invisible taiwan-clone company.
