[ts-7000] Re: TS7300, Serials and pthread

["pa_ie2000" <>]

Hi Charlie,
     I rewrote the code using __REENTRANT, used strtok_r where
appropriate, and included POSIX_SOURCE.

     No luck.

     I put a delay of 30 seconds in before starting the second thread.

     When I run the program, the first thread works fine, sending and
receiving from COM4. When the second thread starts, reading COM3, I can
no longer read from COM4.

     Code is here: http://www.andronics.com/download/aga.zip

Paul.
