DIALM will sometimes tell you you have no modem connected when you really do.
This is a problem with the way BASIC opens the COMM port. It is looking for
the DSR (data set ready) handshake line to go TRUE. If you have this problem
look in your modem manual for a switch that changes the way the DSR line is
set up and try changing it. Newer modems do not have toggle switches - the
change is made by sending a command to the modem. But since DIALM thinks you
don't have a modem you have to send the command before you execute DIALM.
There are 2 ways to do this, by using a terminal program that is able to
communicate with your modem, or directly from the DOS prompt.
Using a terminal program that is communicating with your modem, type:
AT&S0 [CR]
AT&W [CR]
where [CR] means press the RETURN or ENTER button.
The AT&S0 sets up the DSR line and the AT&W stores the info into non-volatile
memory if your modem is so equipped. This means you will not have to do this
again unless your modem is re-programed by some other command at a later time.
Or at the DOS prompt type:
ECHO AT&S0>COM1: [CR]
ECHO AT&W>COM1: [CR]
If your modem is connected to the COM2 port substitute COM2: for COM1:.
I have included a batch file DIAL.BAT which should accomplish the above and
then execute DIALM. (You may have to edit it to change the port number).
