You need to define
void sendDcsBiosMessage(const char* msg, const char* arg)
so that the string msg, followed by a space, the string arg
and a newline gets sent to the DCS-BIOS import stream.

In this example we send it to the serial port, so you need to
run socat to read the data from the serial port and send it
over UDP to DCS-BIOS.

If you are using an Ethernet Shield, you would probably want
to send a UDP packet from this subroutine.
