Launch Windows command window....

[Ernesto]

I'm trying to launch a seperate telnet window from within my python
program. The command I thought I was supposed to use is below:

os.system("telnet.exe -f C:\Folder\output.txt localhost 6000")

This creates a telnet window inside the current window. This is not
desirable. I need it to launch a seperate command window for telnet
output. Any ideas ?

I'm one step closer...

subprocess.Popen("telnet.exe -f C:\Folder\output.txt localhost 6000")

is improved, but still doesn't launch a SEPERATE window...

This should work but only lightly tested.
subprocess.Popen("start telnet.exe -f C:\Folder\output.txt localhost
6000",shell=True)

You don't say what you are trying to do but if you are trying to drive
telnet maybe you want the pexpect module.

I've never had the need to use it myself so I can't offer any other
advice.

Thanks a lot, but this still didn't launch a seperate telnet window. I
just want the telnet window to open up and do "it's thing" in the
background. Thanks again.
