Folks, the OP isn't an expert. Please test your scripts before posting!

I don't have everything I need to test this fully, but here's a
variant of the above that's at least syntactically correct:

from telnetlib import *
host = '10.128.59.63'
port = 7000
t = Telnet(host, port)
def flush():
  t.read_very_eager()
def sendCmd(cmd):
  t.write('%s\n' % cmd)
  return flush()
flush()
print sendCmd('*IDN?')
print sendCmd('*OPC?')

It's written for Python 2, so use that interpreter.
