This option makes it possible to:
 View important information about the modems connected to the device
(the modem must be set in the device parameters),
 Verify that the modem settings are correct by simple testing the
connection to the master communication point (modem) of the dispatch
centre (regardless of the timer setting and calls of the internal timers of the
device).
For modem communication, also some diagnostic data is displayed.
In the first step, the modem is selected (the device allows for connecting no more than 2
modems, one internal and one external). The following options can be selected for each of
selected modems.
