Actually, I ended up using stdin.write('...\n'), and it works as expected:
#
# Set WindRiver environment for VxWorks 6.4
#
wrenv_path = "C:\WindRiver\wrenv.EXE"
args = [wrenv_path, '-p', 'vxworks-6.4']
proc = subprocess.Popen(args,
shell=True,
stdin=subprocess.PIPE,
stdout=subprocess.PIPE
)
proc.stdin.write(str.encode('wrws_update -data %s -l %s -b clean\n' %
(workspace, self.target)))
output, error = proc.communicate()
print(output)
print(error)
You can keep using stdin.write until you call communicate() this allows
you to write certain commands to the stdin for the process you launched.
Note: wrenv.exe is actually a shell like cmd.exe.
The above code is written for Python 3.1.
Thanks for the help.
