It would appear that on Jun 4, Ross did say: > Perhaps you need pulse instead of tone dialing? If that is the case try > setting Dial Command = ATDP Thanks for the suggestion Ross. Though I don't see how that could be it... All of my telephones use tone not pulse (I just double checked the one on my desk, it's switchable, but the switch is set to the clearly marked "tone" setting. None the less, I suppose the modem itself might be malfunctioning in some way that prevents tone dialing. So while I doubt pulse dialing is the answer, I shall test this theory. . . .

ATDP7340102 ERROR --> Invalid dial command. --> Disconnecting at Fri Jun 4 00:07:41 2010 UnderTree =-> Nope, wasn't that. {sigh} I do wish I could be sure what's wrong. If anybody familiar with zoom brand external modems could confirm that the wvdial.conf I included in my previous post "SHOULD" work, I might conclude that my zoom modem may have developed a malfunction during the years it spent collecting dust in the junk box under my desk. In which case, I still have about a week to return the $39 usb/serial adapter to staples where $59 will get me a new zoom v92 usb modem. But if it turns out that there is something wrong with my wvdial.conf that's causing the problem, (rather than a defective serial port modem) then I've got better things to do with the $20 difference. -- | ~-~ ~-~ Guess I just don't know. | <?> <?> Joseph (the Wordy) Philbrook | ^ J(tWdy)P | ___ <jtwdyp@xxxxxxxx> <sigh>
