6.2.7 Manual selection of the viagraph communication (COM) port
The manual selection of the communication (COM) port might be necessary, in case of:
- multiple connections to different via devices are possible, but with the
Connect to device
search only the first found device is automatically connected.
- several modems with virtual COM ports are installed at your computer. Viagraph always
offers only the first found modem, which is the inappropriate one for a GSM connection to the
viasis device.
- several Bluetooth connections were established in the past, each with a COM port number,
some viasis with Bluetooth modem are in reach, but only the first found device is automatically
connected by viagraph.
In this cases or a combination of them, please have a look in the Windows
Device manager
(see chapters 6.2.2 and 6.2.3), particularly in the device classes
COM&LPT
,
Bluetooth devic-
es
and
Modem
to find the COM port number of the wished viasis device or modem.
