At this time I use this:
os.popen(command)

The Problem isn't the reading and writing input-/outputstream, it's the
timing(I think). I make a 'cvs login' then I'll be asked for the cvs
password and the answer of this question fails. Perhaps I've to use the
tty or ptty module of python, but I don't know how. I'm searching a way
to handle his problem. I hope someone had similar problem (i.e. by
writing a frontend for ftp,telnet,ssh,... (for interactive applications)). 

the Python version is 1.5.2 (I think! It is a pool with 20(?)
workstations, different OS (Linux and Solaris, different versions)).
I think popen2 is available python-version>2 and if it exists another way
(as upgrade Pyhon) to solve the problem I'll use that way.

Insteat, if you know a way to solve my problem by useing popen2 please give me
a short example.
