:SYSTem:COMMunicate:SERial1:BITS?
:SYSTem:COMMunicate:SERial2:BITS?
This command sets the duplex state of the specified port. Use this command
when you cannot see on the computer screen the characters you are typing for
your command.
Expanded Syntax
:SYSTem:COMMunicate:SERial1:FDUPlex ON or OFF
:SYSTem:COMMunicate:SERial2:FDUPlex ON or OFF
Parameter
ON enables echoing of the characters you type (i.e., when typing a command,
the ON state allows you to see on the computer screen the characters you type).
OFF disables the echoing of the characters you type.

SYSTem:COMMunicate:<port>:PRESet sets the duplex state to ON, which is
the factory-default state.
