Yaesu FT-991a ARDOP Winlink
I assume you have installed the Yaesu com port driver from the Yaesu.com website and you know the com port numbers of your Enhanced port and your Standard port. I assume you are using a USB cable from the computer to the radio and not an RS-232 cable. I assume you are not using an external sound card interface such as the SignaLink or Rig Blaster.
If the computer will not set the frequency and mode for Winlink ARDOP, open the ARDOP Winlink Session. It will take a few seconds for the session window to open and load. The ARDOP_Win Virtual TNC will also load in another window. That takes a few more seconds and the ARDOP_Win Virtual TNC will probably start minimized.
