Hi,
What I want to do is create a module that offers a generic set of
functions (send, recieve, etc...) and reffers the request to the
correct module (rs-232, tcp/ip, etc..).
I want all this to be unseen by the script that calls this module.
I want the script to specify the communication type, and
you could always just remove those special characters (\n \t ..),
remove spaces, read both files and compare string. I don't this is the
best way of doing this... but maybe a combination of this way and yours

compare line by line

Hi, I have a question for the experts of Python for series60!
When I use the ".connect" method of the socket, a list with all
connection available pop-up, and, after selecting one, the soft go on.
My question is that: Can i use the ".connect" method passing connection
name, resulting in a connect
I don't think there is direct method. On Linux you can inspect file
/proc/cpuinfo to determine the installed cpus.

Yeah i have already asked it, but, i think i can set before the
.connect method, a connection as default, and, when connected, resore
default connection!
