Limitations for GCS Commands
More than one command mnemonic per line is not allowed.
The number of characters per line is limited to 256 byte (1 character = 1 byte). This means that the
number of arguments following a command mnemonic is limited to 32.
Example:
If you send
TWS 1 100 1 1 200 1 1 300 1 1 400 1 1 500 1 1 600 1 1 700 1 1 800 1
1 900 1 1 1000 1 1 1100 1
the controller will return error 24 ("Incorrect number of parameters") when you ask with the ERR?
command afterwards because the number of arguments is 33.
