How to test series communication?

Hello, everyone,

I have used the "devc-serusb2" driver for a USB-RS232 convertor, and now I want to know if the USB-RS232 convertor works right or not.
Is there any software or simple code available for this? The software can sent some data and then receive and show the data on the screen. Can qtalk do this? and where can I find qtalk?

Thank you very much!!


You can try just with and ‘echo’ and ‘cat’ /dev/your_port. Before you should configure it to the right settings.

Ok, thanks,
I will try it,
but where can I find the qtalk? In launch menu?

Just type qtalk in a shell

thanks a lot!!
