When working with AT Interface, or vSP UART Bridge example applications, how can I break out of a vSP UART bridge connection using the ^^^^ escape sequence in UwTerminalX with the 250ms delay specified, as it does not seem to be working?

When working with UwTerminalX, note that by default LineMode is enabled. With LineMode enabled, any data entered is not sent until the [Enter] key is pressed, as shown below:

To break the connection you must first disable LineMode, then when each character is entered it will be sent immediately over the bridge connection, without the need to press the [Enter] key. Now when four ^ are entered with a slight delay, the first three will be sent over the bridge connection, but the fourth one will break the connection, as shown below:
