MAKING A NULL MODEM CABLE FOR 9-PIN TO 25-PIN PC SERIAL CONNECTORS
------------------------------------------------------------------

Some IBM PCs and compatibles use a 9-pin connector for serial connec-tions.  
When you wish to connect such a machine to a DigiBoard cable, you will need a 
cable or cable adaptor configured as follows: 


     9-Pin                                             25-Pin
