The external device command controls the transmission from the MICRO/I or Touch. The commands are Transmission Prohibited
and Transmission Allowed. The Transmission Control commands are the same as the general X-ON and X-OFF commands. There-
fore, you can use DM Link 1:1 Communication with an external device that can perform X-ON and OFF control without making any
settings.
