pyserial and file open conflict?

[p.wallstedt]

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

Are you sure you need to reinvent the wheel ? For example, pppd has the
"chat" application:

Your problem is in line 117 of your program.

Maybe you have enough time to read this:

"Do you have a sense of irony?" he asked, already knowing the answer.

Grant - "Do you have a sence of appropriateness"? he asked, already
knowing the answer. I had no idea this is a comedy club. I might argue
that my reply was also some sort of humor, but you clearly didn't see
it that way. Maybe you should try living according to the rules you
make for others?

Diez - Did you mean the section which covers Asperger's Syndrome?

I'm just being a hacker here guys ... according to the guidelines.

It's amazing how such a simple question gets derailed immediately.
Without any light on the subject whatsoever.

Try asking about your problem again. Think before writing. Read your
text after you write it. Tell what you are trying to do, how you are
trying to do and what's the buggy behaviour. Copy the relevant part of
your source code here.
