If the first field is not a known command (as listed above) or SW field is different from the serial address programmed in the switch memory, the command will be ignored. If the SW field corresponds to the serial address, but the syntax is wrong after this field, the switch will answer with ?<CR>.

Syntax example:

CS 01,05,02<CR> (insert the space and commas as shown)

which means “At the switch with unit address 01, connect CPU port 05 to user port 02” The switch will answer with:

∗<CR>
