There seem to be plenty of options in the 2400 baud arena, but now we're getting greedy and are looking at some of the 9600 baud modems which are beginning to become available. Does anyone have any experience with 9600 baud modems (preferrably asynchronous)? The only companies I've seen advertise so far are: Electronic Vaults (Reston, VA): upta 96 (asynchronous) Universal Data Systems (Huntsville, AL): UDS 9600 A/B (synchronous) (We just obtained a UDS modem for evaluation (using their EC-100 synchronous -> asynchronous converter) and had no trouble getting it to work here in the office. We haven't tried it over long distance lines yet.) It appears that there are some proposed standards for these modems (CCITT V.29 & V.32). I've seen some proposed CCITT standards (V.29 & V.32) mentioned in the literature for these modems. Does anyone know just what these standards standardize?
