Hi Bill,
By response, do you mean acknowledge of receipt like "message sent", or
a response from the bank server like when you send "Bal" and you receive
"Balance as of today is 10 Million Dollars and no cents".. it is very difficult to
find a working example of the later because it requires many things including
server side programming, SQL queries and so on... however, if you don't want
to parse and process the response , and only want to see your
balance... etc, then the job is much easier, because you will only send a simple
sms message like you send to your friends, and the computer will process it and
send you back the response. I would suggest using VS in the server side and
specially Visual Basic paired with MySQL or even Ms Access.
