I have a CPI Viva 56k LC-SM and am trying to get it to work, I have all the init commands etc but cannot get it to work. I can query it and get a response, the ATI's have no information...and the ATZ string doesn't work, i tried another init string called ATI and that did not work either.. It is set to the right port and everything it just doesn't respond...any clue on this one? I have heard that CPI is more software driven so maybe this cpi modem is winmodem-ish Any clues? Dave
