RMC Components
The RMC resides in an independent microprocessor on the
system motherboard and allows a remote operator to connect to
the system COM1 port from a modem or from a serial terminal
or terminal emulator.

The RMC logic is implemented using an 8-bit microprocessor, PIC17C44, as the
primary control device. The RMC PIC is programmed with code to control
access to various environmental status bits.
You can gain access to the RMC as long as AC power is available to the system
(through the wall outlet). Thus, if the system fails, you can still access the RMC
and gather information about the failure. The jumper position shown in Figure
4–1 is the default position set in manufacturing which enables the RMC.
