Serial unable to connect to Modem

P: n/a
mm
Hi,

I have a modem connected to the serial port and I can communicate using
Windows HyperTerminal.

When I try to send a 'AT' command using the SerialPort object I get receive
timeout errors.

Any help would be much appreciated.

I have developed a similar problem in the last two weeks I believe. I can't
connect modem to modem. I notice that as soon as I hit CONNECT the properties
change from 7-even-1 to 8-N-1. I have changed every default and individual
setting I can find but it always changes back. Could this be related to your
problem? I wonder if it is something that has been changed with an automatic
update?
