in reply to serial port bridge (virtual)

Faking a serial port like that would be tricky in any language, but particularly tricky for a scripting language that isn't designed to run in driver space. Depending on the degree of control you have over the applications you may be able to write a Perl daemon that connects to the GPS serial port and provides pre-digested GPS information to applications.

    I have found a solution all be it not very elegant.

    I'm not using perl at all.

    I used mkfifo to create two files

    then "cat /dev/ttya | tee /fifo.file1 | cat > /fifo.file2 &"

       cat /dev/ttya | tee /fifo.file1 | cat > /fifo.file2 &

      You can most likely get rid of the second cat, because '| cat >' is the same as '>', wrt functionality: 

      $ echo foo | cat > myfile
$ cat myfile
foo

$ echo foo > myfile
$ cat myfile
foo
