The first station in this example is identified as green. It is set up on com 1 at 2400 baud, no
parity, eight data bits and one stop bit. BIN, DSO, CD0, and CS0 are various configuration
parameters that must be in the string. The TWI station is configured as a remote unit. A
modem would be connected to com1 set at 2400 baud, no parity, 8 data bits and one stop bit.
The ATE0QV1M1X4S0=0 is the modem configuration string required by this particular
modem. The DT1,214,234-1309 is the phone number where the remote unit and its modem
