I am a satisfied, long-time, U.S. user of IVM who recently upgraded from XP to Vista Ultimate (32-bit). I am at my wit's end trying to locate even a single modem (low-profile PCI or USB) that will work with IVM under Vista. If anyone with NCH (or anyone else) can point me in the right direction, I'd surely appreciate it. I'd hate to stop using this wonderful software just because I've moved to Vista, but I've now purchased and returned at least 5 modems in an effort to find one that works. And, yes, I have done the appropriate settings and diagnostics, and although at least one of them reported supported for the Rockwell voice command set (AT#CLS), none was recognized by IVM. Thanks in advance for any information.
