Using a cell phone to send Text Messages

[zLon]

I'm having a few issues and I'd like some feedback on and your experiences. Also, has anyone gotten an off-the-shelf phone to work?

I have a Samsung Galexy S4 Active on AT&T Mobile.
Windows Server 2012R2
Downloaded Samsung USB Driver for Mobile Phones
It is active on COM3.

I used 'Visual Basic Terminal' to do a simple 'AT' command to get an 'OK' and I did not get it. I also tried Hyperterminal and it also failed to produce an 'OK'.

When I go into the Control Panel/Phone and Modem/Diagnostics/Query Modem, I get:
ATQ0V1E0 -
AT+GMM - AT+GMM
SAMSUNG-SGH-I537
AT+FCLASS=? -
AT#CLS=? -
AT+GCI? -
AT+GCI=? -
ATI1 - I537UCUCOC6
ATI2 -
ATI3 -
ATI4 -
ATI5 -
ATI6 -
ATI7 -
ATQ0V1E0 -

So it appears to be responding to Windows. Should I try a different driver? Different phone? Do I need DUN installed on the phone? (I did this too)

I'm not sure which part of the AT command set that devices supports, so there's a test I'd like you to run.

Open a connection to the modem with Visual Basic Terminal, then issue the following commands in sequence (hitting enter after each):

AT
AT+CSQ
AT+CMGF=1
AT+CMGS="CellPhoneNumber" (Note: Include the quotes)
Type the text of a test message.
Ctrl+Z (press this key combination on your keyboard)

Please let me know what happens after each command.

I tried to send those commands, however I never got a response from any of the AT commands. I'm guessing that I don't really have a "real" serial connection.

When PageGate sends something to that serial port, I get the following:

I guess it is time to start looking for a Multitech GSM device. If anyone has a unit that works well, please share you model number.

Thanks for your assistance,
