The WSTK boards factory programmed to support 115200bps. This may no suitable for custom firmware thus there is a possibility to set the baud rate to customer specific value.
To change the VCOM speed first it is necessary to access the Admin console on the WSTK. Currently, two methods are supported:
telnet (using Ethernet connection of the board, supported by all board contoller firmware versions)
Simplicity Studio's Admin console access (supported with board controller firmware 1.1.1+ and recent Studio only)
The console commands are identical for both method.
Access through Ethernet network
To access the Admin console through telnet first need to connect the WSTK to an Ethernet network which provides DHCP server.
If the WSTK's built-in DHCP client was able to receive the address and network configuration was successful, the IP address will appear on the kit's LCD screen.
Use that address to connect to the board by telnet program (you may need to enable / install telnet on - refer to your OS manual about details).
The Admin console accessible on port 4902 (replace the IP address with the one appears on your LCD screen):
telnet 10.5.146.86 4902
On successful connection the prompt WSTK> should appear.
Access from Simplicity Studio
To access the console from Simplicity Studio, only the USB port has to be connected. Select the required J-Link adapter, right-click on it and click on Launch console...
When the console appears Switch to the Admin tab at the top then click into the input text box at the bottom press Enter. The WSTK> prompt should appear.
Changing the baud rate of the Virtual COM port
By issuing the help command a few lines of help appears about the usage of the Admin console:

To change the Virtual COM port baud rate to 9600bps issue the following command: serial vcom config speed 9600
There is also possible to set handshaking method by issuing the serial vcom config handshake ... command.
