Operating Modes

The RMC can be configured to manage different data flow paths

defined by the com1_mode environment variable. In Through mode

(the default), all data and control signals flow from the system COM1

port through the RMC to the active external port. You can also set

bypass modes so that the signals partially or completely bypass the

RMC. The com1_mode environment variable can be set from either

SRM or the RMC. See Section 7.6.1.
