Hi Phil,
For the C-based SF, I started it with:
./sf 9002 /dev/ttyUSB0 57600
For the java application, I have:
-comm s...@localhost:9002
>From SF side, I can see the java application connects to the SF and
displays:
clients 1, read 0, wrote 0
But there is no incoming data for the java application. I have double
checked this application with a actual serial port (on a dock station for
the same laptop), it worked fine for both java-based or C-based SF.
Thanks,
Jason
