SERIAL PORT WRAP PLUG
|
||
|
||
|
||
In order to test the complete circuitry of the serial port on an
|
||
AST board (when running IBM diagnostics) there must be signals
|
||
coming into the port. This may be accomplished by installing a
|
||
wrap plug on the serial port connector. To construct a wrap plug
|
||
use a standard RS232 DB25 female connector and wire these pins
|
||
together.
