They are just normal modems. I know as I have one. ;-) Gives me about 2/3 of the German ISDN speed of 64000 bps - it reaches 44000 bps - which makes the WWW real fun and CVSUp more enjoyable and cheaper. The one in question is a PCI card from what I read and for such cards one can make the hardware cheaper by putting part of the processing into a special driver which makes it appear like a normal COM port modem to the system and is just noticeable by reducing the available main CPU power a bit when in use. W/o such a driver (under FreeBSD for example) one can't use it then. As far as I understand the problem with this is that one can't write a driver w/o documentation (I guess no one will doubt this :->) and it seems for such devices the only documentation for the hardware is the binary version of the Windows driver. One would first have to reverse engineer the Windows driver. :-( Of course one might envision a hybrid version where one does this trick over a serial port but I hope no manufac- turer makes such an insane device as then the serial port has to be faster I think and then it might fail with not so good cabling which just works with normal modems for example but can't stand higher speed.
