##LazSerial v0.1 ##Serial Port Component for Lazarus (windows and linux). ####by Jurassic Pork 03/2013 and

Patch for LazSerial to work with OS-X by rphoover

see: http://forum.lazarus.freepascal.org/index.php?topic=32632.0

As a part of the patch, a new property was added to the TBlockSerial class in synaser.pas, added as NonBlock. The NonBlock property is for Unix users (Linux and OS-X included).
When NonBlock is True, the call to the FpOpen method in TBlockSerial.Connect will not block when an of CTS, DSR, or Carrier are not active.

Based on :

  • SdpoSerial v0.1.4 CopyRight (C) 2006-2010 Paulo Costa [email protected]

  • Synaser library by Lukas Gebauer

  • TcomPort component

####Features :

  • changed baudrate values.
  • changed stop bits new value : 1.5
  • new event : onstatus
  • new property FRcvLineCRLF : if this property is true, you use RecvString in place of RecvPacket when you read data from the port.
  • new procedure ShowSetupDialog to open a port settings form :
  • the device combobox contain the enumerated ports.
  • new procedure to enumerate real serial port on linux ( in synaser).

Demo : a simulator of serial port gps + serial port receiver : you can send NMEA frames ( GGA GLL RMC) to the opened serial port (start gps simulator). You can change speed and heading. In the memo you can see what is received from the opened serial port. In the status bar you can see the status events.

tested with windows 7 and Ubuntu 12.04

if you haven't serial ports in your PC you can use virtual ports :

  • 1 - WINDOWS To simulate a paired serial ports on windows : com0com ex :
  • 2 - Linux To simulate a paired serial ports on linux : socat ex : socat -d -d PTY: PTY:

To connect to a bluetooth GPS on Linux echo connection to a bluetooth GPS(/dev/rfcomm0)

sudo rfcomm bind 0 xx:xx:xx:xx:xx:xx 1

Sorry for my poor english but it isn't my natural language.
