RX TX problem HELP PLZ

[kavinyang]

I connected my serial port(from PC) to my max232 serial board
and i connected the RX and TX of the max232 serial board together; so that when tested data will be send back to hyper terminal

With that mentioned i can't seen to type anything on hyperterminal
i change the setting to COM1 (check device manager and COM1 is the port) and COM1 port is connected to my MAX232PCE board

The problem is how come i am not able to type anything on the keyboard and be display on hyper terminal? i bought a new max232 chip and i check with multi meter "i am feeding 5V to the board which supply the max232CPE" but i wasnt able to type anything on hyper terminal

Is it my serial port? I try many serial, still the same problem

And i'm not being able to test that, because i want to know is when my program is sending to PIC, my PIC respond and send something back to Hyperterminal

plz help me


plz help me again

Write a tiny PIC program that just says "Hello World" from the PIC to the PC over and over every second or so. That will test one way communication, RS232 driver, baud rate, crystal speed, Hyperterminal, and most of the wiring.

Once Hello World works you can try receiving data with the PIC.

If you want to see what you've typed in the Hyperterminal, you need to go to properties => settings => ASCII Setup => and check the "echo typed characters locally.

For you communication problem, I'm not sure what's wrong. Make sure your TX and RX are connected to the right pins.
