Besides software handshake is so much simpler, and you only need a 3 wire cable, so I will only comment on the 3 wire method.
First check your machine constants, they should look like this:
N 770 = 0 (DIO / DNC)
N 771 = 0 (0= ASCII)
N 772 = 1 (DIO Recognition Automatic)
N 773 = 2 (DIO Flowcontrol 3 wire)
N 774 = 30 ( DIO Leader/ Trailer)
N 775 = 1 ( Stop Bits 1 or 2 )
N 776 = 2400 ( Baud Rate)
You must also make a 3 wire cable like this:
9 Pin PC 25 Pin CNC
Pin 3 ------------> Pin 3
Pin 2-------------> Pin 2
Pin 5-------------> Pin 7
Constant N770 must be set to "0". You cannot use DNC mode with serial communication. It requiers special sofware and setup from DMG.
To output a program, simply press the "PROG MEM" key, then F5 "ID DIR", then "DATA IN/OUT", then F3 "OUTPUT".
