6.1.5 Additional synchronisation methods in InputVlCamera

Currently the InputVlCamera module only supports synchronisation via a TCP network, some other methods of synchronisation would be desirable. Most notable are:

• Serial connection, which uses a null-modem, RS-232 serial connection between the two computers to communicate the synchronisation messages.
• Serial external trigger, which would use a double-pole, single-throw (probably momentary) switch attached to the serial ports of the computers to trigger when images are taken.
• Standard external trigger, which would use the external trigger found on some webcams (such as the cam) to trigger the capturing of the images.
