Hello,
Thanks to all that try to help. For Feedback purpose,

Now it works, but not with Serout2 but trough debug,

' Set Debug pin port
DEFINE DEBUG_REG PORTE
' Set Debug pin bit
DEFINE DEBUG_BIT 0
' Set Debug baud rate
DEFINE DEBUG_BAUD 2400
' Set Debug mode: 0 = true
DEFINE DEBUG_MODE 0

debug master,destino,posicao 'this works


disp_pos var PORTE.0 'TX
dir_rs485 var PORTE.1 'RS485 tx Mode
high dir_rs485 'set to transmit mode
serie_in var PORTE.2 'RX 'not need in this project

serout2 disp_pos,396,[master,destino,posicao] 'dont't work

Not idea why serout2 not work.
