2009-01-02 05:17:14     simple serial programme

Hi

 

I am a nubie to gnu C++, and uclinux so the learning curve is steep!

 

what i am trying to do is a simple serial port test, receive a character on uart 0 and tx on uart 1 and vice versa.

 

what ports do i need to open (i see from some posts this is now TTYBF0 and TTYBF1 is that correct?) what methods can i use on the file open?

 

any help greatfully received

 

TIA anthony

thanks for the pointers.

 

this refers to ttySx in a post on serial problems you said to use ttyBFx

 

is it either or, which is correct?

 

TIA anthony

it's a generic document.  the default on x86 desktop systems tends to be ttySx.  you use whatever serial device is appropriate.  the Blackfin UARTs are ttyBFx.
