oratns Service not responding

Hi team,

I have recently configured xymon and need a suggestion on setting up alert
for oratns.
Oracle tns is having port number 1527 as per
$ORACLE_HOME/network/adminlistener.ora

I have declared it hosts.cfg and given the below service definition in
protocols.cfg,but it is showing status red in xymon

[oratns]
   port 1527
send
"\x00\x57\x00\x00\x01\x00\x00\x00\x01\x36\x01\x2C\x00\x00\x08\x00\x7F\xFF\xA3\x0A\x00\x00\x01\x00\x00\x1D\x00\x3A\x00\x00\x00\x00\x00\x00\x00\x00\x00\x0

Please suggest if any changes to be done in above connect string.
