Interesting, but why would you use TELNET for that?  Telnet is
simply one of many possible protocols, whereas you need only
open a socket to the port to see if the host is responding.

from socket import *
s = socket(AF_INET, SOCK_STREAM)
try:
    s.connect((host, port))
    print 'host connected'
    s.close()
except error:
    print 'host not responding'

Should basically do the same job ...
