Communicate With GSM Via Modem Using USSD Codes

We need a very good Java programmer who can work with AT commands in Modem.

Clearly, the developer need to develop a java program which can pull request

from mySql table . The request will Contain phone number and recharge amount.

Based on the phone number (which also tells who the Gsm Carrier is) the program

will select the appropriate carrier and send USSD codes ( some codes will be interactive and some direct)

based on the USSD return ,the program need to update mysql table flag.

This is a mobile recharge system where a topup SIM will be place inside a MODEM.

And the java program can DIAL USSD code using the modem and AT command.

Alternatively, you can install other intermediary Linux software to communicate with

the modems and use their Api's

We are looking some urgent work, so, if you have something ready you get prefer.
