KeyCode Open API Specification

If a KD-IP922ENC or KD-IP922ENC port is configured for use in KeyCode Open API mode,
the device will listen on a dedicated TCP port for that particular I/O port.
The user application can then make a TCP connection to that port and send to and/or
receive data from that I/O port.
The default TCP port 4580 is used for I/O port configuration commands. The Configuration
port assignment is flexible, and can be adjusted using the SetTCPC:<TCP port#>\r.
Separate TCP ports are used for I/O port traffic data. IP Port number assignments for I/O
ports are flexible, and assigned using the SetTCPP:<port#>,<TCP port#>\r.
It is recommended that TCP Port assignments always be be no lower than 1024.
All I/O port traffic is limited to only one TCP connection at a time.

Command Protocol
All commands/responses are in ASCII text and are terminated with a (\r) carriage return.
›
All commands written in the following format:
›
COMMAND:<port#>,[<parameter 1>[,<parameter 2>,]...]\r
»
Here COMMAND is the command name and <port#> is the I/O port number from 1 to 3.
›
<parameter> will vary depending on the command.
For example, to set port 1 to IR sensor mode, the command is
»
SetIRL:1\r
»
All commands are case sensitive
›
All commands do not include "<", and ">" characters
›
All commands contain no spaces
›
