8051 Gsm Interfacing

i wanted to know how exactly handshaking signals (RTS and CTS) be included in the program.

we are using a wavecom modem that use AT commands.

we have also included MAX232 for ttl to rs232 conversion.

command to accept call is ATA. i wanted to know whether to trasmit ATA command as a string through Serial port(TXD) or transmit chatracters A,T,A separately or is there some other equivalent code that is being transmitted when using the hyperterminal

Thanks
