If the first field is not a known command (as listed above) the command will be ignored. If the syntax is wrong after the first two
fields (first 4 characters), the switch will answer with ?<CR>.
Syntax example:
(insert the space and commas as shown)
CS 01,02,05<CR>
which means "At the switch with unit address 01, connect user port 02 to CPU port 05"
The switch will answer with:
∗<CR>
