blackberry to v/com port app using AT commands for SMS

This should be a fairly simple app to develope since it only requires data transmission... What i'm looking for is a custom blackberry app that can transmit SMS data using AT commands from external software (ozeki ng sms gateway) to the blackberry for sending and receiving SMS. I am using software called ozeki ng sms gateway, which requires a gsm modem, com port or http connection to send SMS and I'd like to be able to use this software to send SMS through multiple blackberry handsets connected via USB and/or bluetooth. ozeki can connect to a com ports for sending, but does not support blackberry, since there's no comport created. what i'd like the app to do is create a virtual com port that can be connected to the ozeki software and then ozeki software can send/receive SMS via the comport through the blackberry. you can download a 20 day trial version of ozeki from their website for testing. any questions please ask.
