Hi, try the code below, I have no problems with the serial port.

PRIVATE Sport AS SerialPort
CONST None AS Integer = 0
PRIVATE Rx AS String

PUBLIC SUB Form_Open()
  Sport = NEW SerialPort AS "Sport"
  Sport.PortName = "/dev/ttyUSB0"
  Sport.Speed = "19200"
  Sport.Parity = 0
  Sport.DataBits = "8"
  Sport.StopBits = "1"
  Sport.FlowControl = 0 

  TRY
    Sport.Open()
         
  IF ERROR THEN
    TRY Sport.PortName = "/dev/ttyS0"
      Sport.Speed = "19200"
      Sport.Parity = 0
      Sport.DataBits = "8"
      Sport.StopBits = "1"
      Sport.FlowControl = 0
      Sport.Open()
    IF ERROR THEN
      Message(" Onboard Uart Comm 1 not found -- PROGRAM TERMINATING")
      QUIT
    ENDIF    
 ENDIF
 
END

'******** Get RS232 data ********

PUBLIC SUB Sport_Read()
  SLEEP 0.025

  TRY READ #Sport, Rx, Lof(Sport)
 
  IF ERROR THEN
    GOTO NoRx
  ENDIF
 
  IF Len(Rx) > 8 THEN
    ListBox1.Add(Rx)
  END IF

NoRx:

  Rx = ""
 
END

PUBLIC SUB Form_Close()
  Sport.Close()
  QUIT 
END

Regards
Mike
