With TEXT: 2975 cps in v.32bis mode for a 500k file. With an uncompressed EXE file: 1763 cps for 220k And then the bad news... one of the v.32bis Duals developed a problem with the circuit that detects RING signals -- it started giving a false ring intermittently when the modem went on-hook (my terminal software doesn't like data coming in during a pause in the autodialing process, effectively making the modem useless for autodialing). I called USR yesterday and they had me reload the factory config, then set the unit up from scratch again. The false RING still appeared. They said they'd like to "take a look at it" so off it went yesterday afternoon with the UPS man. USR said there was about a four day turnaround (not too bad) and they'd get her back to me good as new. Other than the RING problem (which I assume has to be some kind of simple component failure -- modem thinks the surge of voltage after disconnecting is really a ring) the v.32bis Dual Standard seems a stable unit. I've had virtually no problems with carrier loss or interrupted transfers. Most of my calls are LD from Texas to California and I use AT&T. (Reach out America -- not a bad deal for $6.70 per hour). I'll be happy to answer any specific questions about these beasts (to the best of my ability) and I'll sumarize for you guys. Mark williams@gamma.is.tcu.edu
