 By default, MacOS will use serial port B for LocalTalk. To enable LToUDP, enable the bridge through the
 'Ports' -> 'Channel B (printer)' -> 'Enable LocalTalk (UDP)', or start Snow with `--serial-bridge-b localtalk`.
+The bridge setting is saved in the workspace, so it is re-enabled the next time the workspace is loaded.

+## Saving bridges in the workspace

+Enabled bridges are saved in the workspace and re-enabled when the workspace is loaded. A PTY bridge gets a new device
+filename every time it is enabled. Bridges specified on the command line (`--serial-bridge-a`, `--serial-bridge-b`)
+take precedence over those saved in the workspace.
