- 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).
