Data buffering

I checked this and the problem is not in UDP client-server. It works great but when I try send the command via TCP my connection is refused. I try to send cmd to the RS485 server. This is the script:

Code:

if not server then  -- local UDP server on port 5432  server = require('socket').udp()  server:settimeout(1)  server:setsockname('127.0.0.1', 5432)    -- serial connection  port = require('serial').open('/dev/RS485', {    baudrate = 4800,    parity = 'odd',    duplex = 'half',    databits = 8,    stopbits = 1  }) end cmd = server:receive() if cmd then function somfy_rf(cmd) serial_server_ip = '192.168.2.15' host, port = serial_server_ip, 10001 socket = require("socket") client = socket.tcp() client:settimeout(1) client:connect(host, port) client:send(cmd) end  somfy_rf(cmd)  if #cmd == 12 then    time = 6  elseif #cmd == 13 then    time = 0.6  elseif msg == set_channel then    time = 0.45  end  os.sleep(time) end

Where is the error?

This is the network configuration of the serial server.
