Notes on commander:

● Any command must not exceed 38 bytes and must be terminated with a carriage

return.

● The user must read back the responses for each command properly and check

whether the command was successful.

● The command format must be followed with the same number of arguments. Also,

extra spaces count as errors.

● All numbers are Hexadecimal represented in ASCII. For example, to send the

decimal number 16 to USBwiz which is 10 in Hexadecimal, you send 0x31 which is

ASCII for 1 and 0x30 which is ASCII for 0. Also, for Hexadecimal numbers A to F,

they must be entered in upper case letters.

● In all command's output description below, will assume the commands succeeded.

n case of failure, the command would return an error code instead of success and

alt. In other words, in any command, a !00 denotes success and the command can

resume operation. But in case of failure, the error code is !xx, where xx is the error

number and then the current command halt and the commander resume processing
