If you use other terminal software or make a manual terminal connection with
viagraph
you need to know which virtual COM port number was assigned to the
Bluetooth device and set the COM port in the terminal program accordingly. This
COM port number can be either found in the Windows
Device manager
, see chap-
ters 6.2.2 and 6.2.3.1 or else with a right mouse click to the device, which was added in
Devic-
es and Printers
, menu item

in the

tab, see also illustration 37 below:
Illustration 37: COM port number of the serial Bluetooth device
The radiation of the Bluetooth antenna and therefore the zone where radio connections are
possible is similar to the radar in front of the display. Directly aside, below and behind the
viasis a connection is only possible if reflectors (buildings, fences or vehicles) are nearby.
Internal Bluetooth modems of laptops, notebooks and mini computers are in
common designed for the connection of peripheral Bluetooth devices like key-
boards, mouse, mobile phones, which are placed close by your computer.
Therefore their radio transmission strength and reception sensitivity is often quite
bad. In such a case turn off the internal modem and invest a few Euro for an external class 2 or
better class 1 USB Bluetooth dongle, with which you can have a much better and stable distant
Bluetooth connection.
If you have already established some Bluetooth data connections to different viasis or more
generally to via devices in the past and these devices are still reachable while you try to con-
nect in
viagraph
with
Connect to device
you may experience the fact that viagraph
automatically connects to the first found via device and not to the device you wanted viagraph
to connect to. In this case you have choose the connection and the device manually, please see
chapter 6.2.7.
