I am using a CC SpeedModem Combo for several months now, running it in my BBS, joining the CC sysop program. If you'll contact CC, say hi from me to Cynthia Murray (you'll probably get her on the phone). First of all, forget about the 38.400. That speed is supposed to be accomplished by an external protocol which is written especially for the SpeedModem {Combo,Champ}. Also forget about compatibility with any other highspeed modem at speeds above 2400/MNP. That out of the way, these modems really do deliver 9600bps when talking to one of their kind, with or without their own error correction protocol. Also you get 2400/MNP5 with any other modem supporting that, and with the SpeedModem Combo 9600bps send/receive fax, too (BitFax software included). As far as I know, current pricing is $279 for the Combo, and $159 for the Champ. They builded their highspeed technology from scratch, with the goal of doing it as cheap as possible. One particulary interesting design decision is that they made the signal processor usable by any other firmware they might come up with. Plans exist to implement voice mail capabilities some time this sommer. These modems come as internal models, configurable in 22 combinations of the port adresses 278, 2e8, 368, 378 and 3e8 with the IRQs 3, 4, 5, 7 and 9. Standard COM1 and COM2 as well as quasi-standard COM3 and COM4 are possible, of course. The modem card looks like a 16450 to your software, but it doesn't really have that UART on it. With DOS and X00, I lock the speed to 19200 and have no problems with it. I also tried to install it in a unix box, but the FAS async driver doesn't recognise the 16450 emulation. The stock asy driver doesn't work very well at high speeds, it especially doesn't seem to do hw handshaking right. If anyone succeeded in using a CC in a Unix/386 box, I'd definetely like to hear about that. Of course, it is a pity that you cannot talk to other highspeed modems with a CC, but that's why it is that cheap (they say that V.32[bis] is very expensive to build). You get a lot of value: 2400/MNP5, 9600 fax, 9600 CSP. Also they start to get wide-spread: EXEC-PC already has some lines equipped with CCs, I heard. I also heard CI$ is considering it. Customer service is excellent, firmware upgrades are free, warranty is 5 (five) years, and you have a 30 day money back guarantee. One warning to overseas, though: here in Germany, I had some problems with Germany's non-standard telephone lines. A change in a resistor value helps for nearly all installations, but I had one case where we weren't able to make the CC work (yet). Note that this doesn't apply to USA (and Canada?) users, I heard they work nicely out of the box over there. I hope this is the kind of information you were looking for. I'm afraid it sounds a bit like sales blurb; if so, please ignore that. Joern. -- Joern D.
