Check connected tcp ports

[buuuudzik]

Hello

do somebody know:
- how can I check currently connected tcp ports?
- how can I reach the socket which is created and permanent used in resident script via event script?

The solution is necessary for Sony Bravia TV. I must have permanent tcp connection to have ability to read status when TV is off. So for this solution I've prepared the resident script 0s:

Code:

require('socket') if not sock_bravia then -- bravia IP ip = '192.168.2.102' sock_bravia = socket.tcp() sock_bravia:settimeout(3) res, err = sock_bravia:connect(ip, 20060) end -- power-status cmd = '*SEPOWR################\n' -- Check status power if res then  res, err = sock_bravia:send(cmd)  if res then    res, err = sock_bravia:receive()    if res then      log('receive OK: ' .. tostring(res)) -- received ok    else      log('receive failed: ' .. tostring(err)) -- receive failed    end  else    log('send failed: ' .. tostring(err)) -- send failed  end else  log('connect failed: ' .. tostring(err)) -- connect failed end os.sleep(5)

But sometimes I want send command e.g. switch on but from event-based script. How can I reach currently port from other script?
