Any clues? Floyd Davidson's answer may also help explain my own, slightly different, false RING problem: while on-hook in originate mode (auto-answer disabled) my modem "detects" dial-pulse clusters of great enough length as RING 's. Eights, nines and zero's always; the lower the number, the less the likelihood of its being considered a ring. I first discovered this while the modem's auto-answer was still enabled (at the modem-specific default of 2 rings) -- I'd place a voice call, or try to, only to hear the modem's answer tone before I had a chance to finish dialing. Setting the right S-register to zero cured the auto-answer problem, but is there a cure for the false RING-detection ? (I know, I know, get DTMF service. No thanks, I save $2.00/mo. w/ rotary.) The modem is from Acer, their 2424 (an MNP-4 300/600/1200/2400 jobby). For any advice, my thanks. -- Fred
