No, you don't need to use the modem control signals. Books exist on RS232 and Visual Basic, though I haven't read them. Try amazon. You'll need to decide if you want a protocol (e.g., a checksum or CRC at the end of your packet), or if you just want to accept the first N bytes received.

google. Also, look for application notes for UARTs.
