Connection with host:

(PC or compatible)
DTR 20
DSR 6
TX 2
RX 3
CTS 5
RTS 4

Alternatively you can just connect the 3 wires in the following way.
Host 25S
(PC or compatible)
TX 2 ........... 2 RX
RX 3 ........... 3 TX
GND 7 ........... 5 GND
pin 4
pin 5
pin 6
pin 20
The simplest way to connect to other hosts (not PC compatible) or terminals is:
Printer
Pin 2- RxData
Pin 3- TxData
Pin 5- Ground
In general as long as the data quantity is not too large or you use Xon/Xoff as flow
control, there will be no flow control issues.
