 Based on  :
- SdpoSerial v0.1.4
  CopyRight (C) 2006-2010 Paulo Costa
   paco@fe.up.pt
 
- Synaser library  by Lukas Gebauer
- TcomPort component


Features :
Changed :  baudrate values.
           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   

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

====================================================================
How to install the component ( lazarus version >=  1.x) : 

1 - Download the file LazSerial.7z (you must be logged in the forum  to see and download the file).

2 - Open the file and uncompress it in the Lazarus/components directory.

3 - Open Lazarus IDE ,  Open the package ( packages/open a package file) LazSerialPort.lpk

4 - Compile

5 - Install

====================================================================

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

to be continued if it is usable ....

Components under GPL are not ideal.  Usually units/components are LGPL (and preferably with exception, like FPC and Lazarus themselves)

Isn't it LGPL already? With different L, if I'm not mistaken...

(it was my mistake I read over the original).

But afaik it was library originally, and GNU tried to rechristening it to lesser because they wanted to make some point, just like GNU tried to redefine the word free.

Unfortunately, don't know how to adapt this component for WinCE platform.. Maybe someone has idea how to do it without manual thread-magic?
