[Synalist] Udp discovering software
Hi. I have wrote a background program for Linux for discovering machines in a
network using udp. The program is necessary because the machines can have an
address in a unknown network and I must find them.
This is the server side program:
TBSUdpSocket.bind('255.255.255.255', '65534');
if TBSUdpSocket.LastError<> 0 then WriteLn(TBSUdpSocket.LastErrorDesc)
else begin
while not Terminated do begin
StringIn:= TBSUdpSocket.RecvPacket(1000);
And this is the client side:
TBSUdpSocket.CreateSocket;
TBSUdpSocket.EnableBroadcast(true);
TBSUdpSocket.Connect('255.255.255.255', '65534');
TBSUdpSocket.SendString('_?'+ #10);
TBSUdpSocket.Connect('255.255.255.255', '65534');
The program can discover machines only if the machines are in the same network
of the client.
How can I find machines in a different network (multicast)?
I have already tried
EnableBroadcast(true);
MulticastTTL:= 10;
AddMulticast('234.5.6.7');

Hi everybody Up till now we always worked with FTDI and Prolific cables and the data that's been sent by our device can be received correctly. Now we started using a new FPGA that has an Exar USB serial convertor on board. http://www.exar.com/connectivity/uart-and-bridging-solutions/usb- uarts/xr21v1410 It is recognized on Linux as a ttyACM* device and the data is for some reason corrupted, bytes are missing and/or transformed.

But, read below: 1) Normal condition, /dev/ttyUSB0 2) Program starts and open USB0 3) Unplug USB0 4) Program closes USB0 and deletes the lock in /var/lock 5) Replug USB0 6) Now the serial interface is not USB0 but USB1.
