Serial Ports
95A Serial Ports
Serial Port A can be used to remote start your system.
Go to JMP4
to get more info... To add more serial devices to your server, you
can install serial adapters in the expansion slots, and then attach the
devices to the connectors on the adapters. In some specialized cases,
an ASCII display station can be attached to a serial connector (see ASCII
Display Stations).
The system board provides two 9-pin D-shell connectors
to the serial port controllers on the system board. The serial ports
do not support current loop.
95A Serial ports use the National Semiconductor's DS75154

The serial port connector can be assigned as Serial 1
through Serial 16, or disabled. Standard usage of interrupt levels
is IRQ 4 for serial 1 and IRQ 3 for any other serial level.
