13. Suggestions and Hints
Below is a list of some of the problems that have been encountered to date along
with possible solutions and/or work-arounds.
13.1 TAS Diag doesn't Communicate with the TAS unit.
If TAS Diag can not establish communications with the TAS unit, the first thing to
check is the Comm port to which the RS-232 is connected. The RS-232 setting on
the File-Properties dialog box should not be changed. However, the Comm (serial)
port needs to be selected for the port connected to the TAS unit. Usually 'Comm 1'
is the correct port. If you have several ports you may have to experiment by chang-
ing the Comm Port setting.
Some Laptops use Comm 1 for Modems and Infrared Sensors. If this is the case
and you have only one serial port, you will need to disable the device using the
Comm Port and enable it for external communications. This is usually done in the
"My Computer" properties or in the BIOS setting. You should call your computer
manufacturer if you can not free up the port.
