Serial Device Interface B (J3)
This serial device interface has a 25-pin male D-shell connector bracket
assembly which attaches via ribbon cable to the pin connector marked
J3
. This connector is located in the upper right hand corner of the board
and it can be used with the same types of devices as serial device
interface “A” described earlier in this subsection. Serial port “B” can be
set via the J8 jumper for one of the three options as shown on the next
page. Note: The interrupt request choices are IRQ3 or 5. If you do not need
serial port “B,” keep the logical port DISABLED.
