Every command consists of nine bytes: one command type of one byte and two
parameters of four bytes each.

Pin Number
On some commands, one or all parameters are ignored.
For UDP, command type and parameters need to be in the same datagram.
Responses to valid commands are always five bytes long, consisting of the returned
command byte and as parameters in the current or updated values. In case of an
invalid command, only one byte with value 0FFh is returned.

When sending a command (TCP and UDP), wait for the response before sending the
next command.

As you can, see there is no Set functions command. Since the pin's function
depends on the hardware in which the WiPort NR device server is embedded, that
configuration is only allowed via 77FE. Settings changed by any of the Set
commands are not stored and are lost when the unit is powered down or rebooted.
