Station Number
The TeleBUS protocol allows up to 254 devices on a network using standard addressing and
up to 65534 devices using extended addressing. Station numbers identify each device. A
device responds to commands addressed to it, or to commands broadcast to all stations.
The station number is in the range 1 to 254 for standard addressing and 1 to 65534 for
extended addressing. Address 0 indicates a command broadcast to all stations, and cannot
be used as a station number. Each serial port may have a unique station number.
