These are the drivers for a "cirrus" 56kv90 external dialup modem(2 files total). It appears to be a generic modem with a cirrus chip that windows sees and has serial connectors. Some numbers on the bottom of my device are: CE 0197X (fcc#?) P/N 18-1c-e51f-1b REG.NO.:6KK TAI-34673-M5-E . I got mine from the old cyberrebate place that went under years ago. It's a great modem-fast dialup and connections and easy driver load.. It also works with the win ME (and others?) generic external 56k V90 drivers included in windows by microsoft; you just load them despite the warning that they weren't written for this modem and they work fine too, but if your like me you prefer the specific driver written for it if possible. Takes 9V power supply at min 500 ma.
