- 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:

echo connection to a bluetooth GPS(/dev/rfcomm0)
sudo rfcomm bind 0 xx:xx:xx:xx:xx:xx 1

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