Transmitting is very easy - simply post a string to the variable ACOMMS_TRANSMIT_DATA and the modem will immediately send that data if it is not currently receiving or transmitting data. The variable ACOMMS_DRIVER_STATUS indicates whether the modem is " ready "(0), " transmitting "(1), or " receiving "(2). The transmission rate and destination can be set by posting the the variables ACOMMS_TRANSMIT_RATE and ACOMMS_TRANSMIT_DEST. If sending non-ASCII data, post a binary string to ACOMMS_TRANSMIT_DATA_BINARY instead.
