T-LazSerial, how can I know PC'com port configuration with LazSerial control?

[Jonvy]

Hi all,
I'm using TLazSerial making a program to use RS232 port send and receive data.
Because this is a common program, it can be used in different PC, and the user can set different port to connect device.

I want to make the program to check the PC's configuration, so it knows how many serial ports and ports number in the PC.So use can choose serial port they want to use from port list.

How can I know this information and let program check.

The program will running on Windows 7 system.

Thanks a lot!

On Windows use Tregistry and HKEY_LOCAL_MACHINE\Hardware\DeviceMap\SerialComm or similar

hello,
use GetSerialPortNames function from the lazsynaser unit (Comma delimited string)included in Tlazserial package.
example : 

Code: Pascal  [Select][+][-]

1. var myComPorts : String;
2. begin
3. myComPorts := GetSerialPortnames();
4. end;

Edit : with TLAzserial you have a form to choose the com port see sertest project.

Code: Pascal  [Select][+][-]

1. procedure TFMain.BPortSettingsClick(Sender: TObject);
2. begin
3.   Serial.ShowSetupDialog;
4.   EditDevice.Text := Serial.Device;
5. end;  

Friendly, J.P
