Sending a character to the serial port?

I am trying to use the hyper terminal program to send a character
from the keyboard to the serial port com1 on my pc. I try to press
any key, but nothing happens on the screen, is it sending the
characters do you think? Do I need to select something from the
menu before I start pressing the keyboard ?

The characters are probably being transmitted. You need to echo the
characters to the screen. Otherwise, they will not show up.

Hello,

Goto the properties for the comm port and make sure 'Flow Control' is set to
NONE. Also, make sure you are connected, it should say on the bottom of the
screen. If you want to test if anything is coming out then just connect the
TX pin to the RX pin. To do this just put a piece of wire from pin 2 to pin
3 (thats assuming your serial port is of the 9 pin type). Now when you
press a key the value will go out the TX pin and then back into the RX pin
and then you should see characters appear on the screen.

If you have 2 serial ports then you can make the following connector:

Port 1 Port 2
===============
Pin 2 --------- Pin 3
Pin 3 --------- Pin 2
Pin 5 --------- Pin 5

Now you can send data from one port to another. Make sure both ports have
the same settings in hyperterminal.
