SendTo_UDP Tool

Description

SendTo_UDP: (free tool) Sends message text to a Target Program listening on a local network UDP Port . This is a method for your external, third party program to send IPC commands to SoundMill, VideoMill and/or FreeStyler DMX Portal. IPC (Inter-Process Communications) must be started on these programs to be able to receive the sent commands.

Tech Notes

IPC is based on the UDP networking protocol. Messages are sent as UDP byte array (byte[]).
IPC - More Information at this link. IPC configuration for SoundMill, VideoMill and/or FreeStyler DMX Portal are essentially the same.
Requires .Net Framework 4.7.2. (More info.)
SendTo_UDP is a Windows Console App (Windows command line tool).
SendTo_UDP does not support IPC message encryption.
