<b>U.S. Robotics modem redial problem: a solution?

Regarding a previously reported (scroll down a bit after going to this link to find the item) busy signal redial problem with U.S. Robotics Universal Modem Script, Kevin Purcell writes: "Put a comma at the end of the phone number. I'll bet that fixes the problem. Some Sportster modems don't detect the busy signal and report busy back to the computer unless some non-numeric character follows the number. This problem has plagued the 1141 series (Sportster Voice for Mac) modems.There is a newer version of the ROMs for the 1141 but I don't know if it fixes this problem. I have the 2/14/95 ROMs."
