pyserial and file open conflict?

[p.wallstedt at gmail.com]

Hi all!

I have a small but rather annoying problem with pyserial. I want to
open a file on disk for reading and then open a com-port, write lines
from the file to the port and then read something back and compare it
to the next line in the file. Should be simple. And it is, apart from
the fact that the file seems to be doubled ...? Or it loops through
the file twice.

If I exclude the "import serial" it works.

Any ideas?

thanks
Peter
