Sounds like it doesn't see the modem. Make sure you don't have any other com programs open (dos programmer, vmail programmer, etc). Sometimes if a modem is plugged in or changed after the program is opened you may have to reset your pc. Can the program dial out at all? or just not connect? You may also want to upgrade to the latest adix programmer, 3.2.9, or the newer windows programmer for the ECS that also can program the adix.
