Operating the transceiver from a computer
Manpack Transceiver 2110 series Reference Manual 409
A typical use for the variable expansion feature is as follows:
Sending and receiving calls
When you make calls using CICS commands, you do not need to use the hangup
command when you are making successive calls, or using the chan or scan
commands. For example, after sending a gpsbeacon command, CICS enables you to
change the channel, then send another gpsbeacon command, without using the
hangup command to close the existing link.
Responses and outputs
CICS is an interface from which random outputs occur, for example, when calls are
received. Additionally, depending on the configuration of the equipment, the order of
responses to commands may change. Software operating on this interface must be able to
adapt to these irregularities to enable correct system behaviour under all conditions. It is
recommended that echo is switched off to avoid intermixing of the commands you enter
with the responses from the system (see page 422, echo command).
Message length in a Message call
The permitted message length when making a Message call depends on the type of call
system, the privacy mode selected, and the character set (see page 430, pagecall
command).

CAUTION
If a response is not received to a gpsbeacon, gpsposition, or
pagecall command (for example, a page call ack to a
pagecall command), you must use the hangup, chan, scan or
call command to receive subsequent calls. Control software using these
commands must take this into account.
