changing a TC65 to PNPSCADA
this setup will requires downloading a setup program to the modem, so the modem should have a SIM card with data on it.
You will need to have:
-The modem connected to your computer via ASC1 (or the red port)
-a Terminal program to communicate to the modem via serial.
-SIM card with data
-PIN of SIM. Default for MTN and Vodacom is 0000 (Sometimes Vodacom is 00000)
For this example, my SIM PIN was 6336
there is a program running on the modem, that you will need to stop.
the easiest way is to this is to copy the stop command into your windows' clipboard
then power on the modem, as soon as it shows the SYSSTART command, paste the
stop command until it acknowledges your stop.
If it comes up with "OM 1.28", you were too slow, and you'll have to start over.
green text is from the modem
blue text is what you have to type

^SYSSTART
at^scfg="userware/autostart","","0"
^SCFG: "Userware/Autostart","0"
OK

The "OK" means it accepted my command, so now the program on the modem will not be started.

at+creg?
+CREG: 0,0
OK

Here I see that the modem is not registered on the GPRS network, because the command returned 0,0.
There may be various reasons for this, but in this case I know there is a PIN on this sim, so I first need to enter that
If it gives 0,1 you can skip the at+cpin command.

at+cpin=6336
OK
at+creg?
+CREG: 0,1
OK

OK, now it is registered on the network

AT^SJOTAP="jsrz","http://www.pnpscada.com/otap/ModemSetup.jad","a:/java","p","p","gprs","internet"

OK
^SYSSTART

I wait for the modem to restart, could take a minute (giving SYSSTART)

at^scfg="userware/autostart/appname","","setup*6336"

You will have to replace the 6336 with your SIM card's PIN number.

Remember to wait until you see "done handling escape"
The modem is not set up until you get that

You can use PuTTY on Windows 10 as a terminal program.

What do I do if there is no PIN on my SIM card?

If the SIM has no PIN on it, you skip the AT+CPIN= command and you can use the default pin (0000) for the setup command as in:
at^scfg="userware/autostart/appname","","setup*0000"
