VB commands for sending SMS using MsComm

Here's a link:  Page 55 of the document is what you want I think:

Simply send the AT Commands like you would any other AT command to a modem.

the minimum AT commands are the followings:
<cr> is Carriage Return (ASCII 13)
the number must be written in international format
+COUNTRYCODE_AREACODE_NUMBER

AT+CMGF=1<cr>

AT+CMGS="+39111999999"<cr>

the phone replies with a different prompt ">"
at this point put the message
this is my message<CTRL-Z>


Of course you should write a little VB routine that sends a command, e.g.

MSComm1.Output = "command string"

and waits for a correct reply before sending another command.

I suggest you to make practice using Windows Terminal emulator and typing AT commands by hand.

Hope it helps
