I have Client Receivables 990215 installed on a single computer. When I attempt to fax to a fax machine in my office the program dials up and makes a conection. The status indicator shows that it is attempting to get connection params. However after several attempts the call is terminated. The error message listed is "bad response from modem". I have two other programs on this machine that have no problems when faxing. How can I resolve this problem?
