The test will send a cod and according the answer we know if service is OK. Let me show a example: telnet 188.8.131.52 6802 After this we need send a command, like S1, SR001...If return 0, mean is OK, if not, we have an error. Anyone have an idea how we did this? Thank you for advance. rc. November 25, 2017 at 8:21 pm #84925 Don JonesKeymaster You could do it exactly like that, actually. No different than a batch file. Or just use a batch file if that's what gets the job done! November 25, 2017 at 11:42 pm #84932 RodrigoParticipant Thank you Mr. Jones, I use the netcap to execute the command. See my simple command line inside a linux RHEL. echo 'COMMAND' | nc 184.108.40.206 1234 > Result.txt I Just install de nc and run it.... simple... Thanks. Att; rc.
