qextserialport BAUDRATE problem

[dheeraj]

Hey thanks for the reply, Actually i will be connecting the RS-232 cable to a target board and then from the the target board it will connected to another computer to check out in its Huperterminal. So i really don't think i can write a program to receive and display on other computer. Actually the test program written in Qt with qextserialport works perfectly fine i can receive and display it on the other computer but i get the problem when i try to view it on the HyperTerminal. It is not consistent i can receive and view the data at times and all of a sudden it stops working. I cross checked all the hardware connections replaced the RS232 cables also but no luck. I think its because of the Baud and other serial comm configuration. The configuration which i have given in the program is not setting at all i think the program is taking some default values on it own. !!


Thank You

Hello

Has any one sucessfully done a program in Qt using qextserialport to send some data or any thing to another computer using RS232 and receive it on the other computers Hyperterminal. I am having serious problems with qextserialport in communicating with the Hyperterminal. I am able to send data using the same program and the same settings to another computer to a program written in Qt to receive from comm port. I downloaded a windows program and tested it in which i can view every thing i send on the other computers Hyperterminal. But no luck with qextserialport. Any body have some idea regarding this problem.


Thank You

G'Day,

I have played with qextserialport a little bit and found that I had to close the serial port then change the baud rate and reopen the serial port again. I also found hyperterminal to be flakey. I used minicom under Linux and Telex under windows when testing my apps.

Hope this helps...

Hey i have a small problem there. Actually i have to communicate with a ATMELTarget board to its Hyperterminal, So if i see the data pass through the systems hyperterminal it will be the same for Target Board. Thats the reason i have to use Hyperminal program to test my program before i cud actually use it on the target board. ??!!


Thank You

I know - this is an old thread, but maybee this helps others.

Under Linux, I also had to to close the serial port then change the baud rate and reopen the serial port again.

Under Window - this didn't work. I had to do it the other way arround. First open the port, and than set the baud rate. Strange - but that's how it works for me.
