Viewing the COM port setting in VCOM
VCOM provides virtual serial COM ports to enable serial protocols to be used over
other protocols, for example, USB and Ethernet. VCOM operates on Windows® XP,
Vista and 7.
When VCOM launches, it assigns a virtual COM port for use by internal devices in
the Envoy™ Transceiver. This port number must be set up in other programs used for
data communication over HF and secure key programming.
To view the virtual COM port setting:
1 Launch VCOM Configuration from Start > All Programs > Codan >
VCOM.
1 Record the value of the COM port used for the device in the Connected
Services frame.
This value is entered as the COM port in the relevant application
communicating with the Envoy™ Transceiver.
NOTE: CICS is used for secure key programming via KMS and KFS.
1 Click Done to close the VCOM Configuration utility.
