hexadecimal. Every command's total length in bytes must be an even number.
After sending a command from the PC to IC-R8600, an acknowledgement is returned. When you send
commands one after another, you need to send the next command after the acknowledgement is received.

Send a writing command from PC to change an IC-R8600 setting.
A writing command is composed of a command number and setting data that follows the command.
The IC-R8600 will return the result as an acknowledgement after receiving a command.
