following setup is required.
Hardware description
A SIM with a data phone number is required, so that a
CSD call can be made from a remote host to the radio
device.

Script
The fully commented script listing can be found below. For

channel goes to on-line mode and can carry the MBUS
traffic. Data is received from the channel, checked to be
