new in v0.3 version Add conditional macros for cpuarm rpi in lazsynaser.pas Hide Active property from IDE Object inspector

new in v0.4 version (02/2021) DeviceClose procedure fixed

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 10 and Ubuntu 20.04 Lazarus 2.0.10

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

V 0.2 01/2017 : BaudRates for UNIX fixed - synaser files units renamed (with laz prefix) scan port for linux improved
