A 0-3 decimal number indicating which S-Link port to use.
A binary string consisting of any number of bits.
This command is used to send data on the S-Link bus which consists of a number bits not evenly divisible by 8. This is not used for S-Link commands, but instead to utilize a S-Link feature which allows you to transmit "IR" signal data on the S-Link bus, which S-Link devices seem to recognize. The commands are identical to the Sony IR commands in their bit pattern, only they are prefixed by a 1110. See the cdpcx200ca.cde device file for more examples.
