Tunnel – Serial Settings
Serial line settings are configurable for the corresponding serial line of the specific tunnel.
Configure the buffer size to change the maximum amount of data the serial port stores. For any
active connection, the device sends the data in the buffer.
The modem control signal DTR on the selected line may be continuously asserted or asserted only
while either an Accept Mode tunnel or a Connect Mode tunnel is connected.
To configure serial settings for a specific tunnel:
1. Select Tunnel on the menu bar, if you are not already in the Tunnel web page.
2. Select a tunnel number at the top of the page.
3. Select Serial Settings. The Serial Settings page for the specific tunnel appears.
