INTERCOM
                   ==============
            developped by Gabriel RIVAT - F6DQM
            =================================== 

INTERCOM is a program initially developped to run with SIMPLEX inside a VHF/UHF
repeater which can be interconnected to other repeaters but it may also be used alone 
or interfaced with an other application which sends ASCII strings of characters on a 
TCPIP link.

The transceiver will then be the remotely programmable equipment
whose listening and emitting frequencies will be set on those of the remote repeater
to interconnect. 

INTERCOM purpose is to remotely program Kenwood transceivers such as TMD700/710/TM-V71 or any other transceiver which features UP, DOWN and PTT commands.
This is done through DTMF codes that the SYSOP will associate to basical commands.
INTERCOM does not decode DTMF codes DTMF itself. This is performed by SIMPLEX 
which transmit the decoded characters to INTERCOM on the TCPIP link.

INTERCOM watches the characters that are emitted by the server (SIMPLEX for example), 
treats them and transforms them into commands in destination of the transceivers.

The available commands are limited to what is really necessary to switch the transceiver
on predefined channels. Too many commands could lead to undesired configuration of the 
transceivers and erratic functionning of the repeater.

Please note that INTERCOM does not replace the Kenwood utility software to set
the memory contents or VFO contents. It only uses these memories and VFOs and switches
them to obtain a desired configuration.

The commands UP, DOWN, PTT towards the generic transceiver are sent through the parallel port. It is then mandatory to copy the driver "zntport.sys" in the directory "windows/system32/drivers". This is done automatically in case you install with the "intercom_install.exe".
