Hi
I am using BSD API to open port . port is usb port in /dev/
My code is as
below
int fd = open(PORT_PATH,O_RDWR | O_NOCTTY | O_NONBLOCK | O_EXLOCK)
if(fd
== -1
printf("\n port open failed");
else
printf("\n
port open success");
The above code successfully open port on MacOS 10.3 and later, but on
MacOS 10.2.8, it is failed to open port.
What may be the problem ?
