TSIPCHAT

TSIPCHAT

is a program that provides full visibility into the TSIP interface.

Source code is provided. The source code (dual windows) requires a
BORLAND C compiler.

Starting

TSIPCHAT

To start the program, type

TSIPCHAT-C1

or

TSIPCHAT-C2

for COM1 or

COM2. the command line is:

TSIPCHAT-Cx

where 'x' is 1 for PC serial port

COM1 or 2 for COM2. This choice can be changed while

TSIPCHAT

is

running using the [CTRL] + [I] command.

As

TSIPCHAT

starts, it displays a list of commands in the upper half of the

console screen (command window) and a running account of automatic
(unrequested) reports in the bottom half of the screen (auto window). It also
sets the serial port to the default settings of 9600 baud, 8-Odd-1.

If the receiver is alive and outputting positions, position reports scroll
immediately in the auto window. If the auto window is empty, type 'v' to
test if the receiver is connected properly to the computer. If the serial port is
properly connected, the receiver responds within a second with the receiver
software version numbers; otherwise “waiting for reply” remains on the
screen.

Report Packets

When a TSIP report packet is issued by the receiver, it is received by

TSIPCHAT

, translated into a printable form and put on the screen. If the

report packet has been specifically requested by a command, it is put in the
command (upper) window; otherwise, it is reported in the auto (lower)
window.

The common automatic reports are the navigation reports: position,
velocity, and health data. The [CTRL] + [O] command can change the
content of these auto-reports or turn them on and off. Other automatic
reports include almanac, ephemeris status, and almanac health page when
decoded; and receiver health, machine code status, and satellite selection at
regular intervals.
