Note: To interface with a serial port on a computer with the RS232 interface, use a NULL

MODEM or CROSS OVER serial DB-9 female to female cable. Do NOT use a straight-through

serial DB-9 cable. To check that you have the correct cable, probe pin 2 on one end and pin 3 on

the other and vice versa to check continuity.
