I have a project working with various SNAP-PAC-R1 for some time. For customer requirements need to send ethernet frames to Multicast addresses (224.xxx).
In that project I'm using UDP frames sent to IPs within the range of SNAP without any problem.
In making the changes necessary to send the frame to a multicast IP, I found that the SNAP is able to send the frame (Whireshark), but the remote computers are not properly.
I think the problem is in the parameter of the frame TimeToLive UDP, which is 1, which does not allow more than one cross swicth / router. TimeToLive Parameter can be modified by any command TimeToLive as SendCommunicationHandle? would be possible to obtain all possible commands that allows this command?
The OptoScript example code:
Status_OpenCom = OpenOutgoingCommunication(SendMulticast);
Status_SendString = TransmitString("MENSAJE DE PRUEBAS",SendMulticast);
Sorry for my English
