        Not really..... Maestro modems and many other pieces of hardware like
to be difficult..... here is the fix:

        On the AT end of the cable, connect pin 6 to pin 20 and pin 4 to pin 5.

        Everybody should know about RS232 connectors... watch for The Data Bus
at the end of this month which will give a good explaination of RS232 - it
even has one or two things in the article which I didn't know..... I will
probably be posting the Data Bus on the 25th, so it should make it's round
trip by the 3rd of April.
