This is for short messages, not long texts. Normal chat talk should work fine. Remote commands too. TCP messages could be longer because they are reliable. UDP packets can be receive out of order, for long messages, but I think the maximum is 64 kb (very unrealiable)

From Microsoft:

When configuring the UDP packet size to be larger than 512 bytes, remember UDP packets must travel through devices other than UDP hosts, such as routers, and these devices may not support UDP packets larger than 512 bytes.


This plugin is to send/receive messages, not raw data chunks.

Thank you Al. I have purchased the plugin. ;-)

512 is fine. I'm going to be using it to send commands ;-)

thanks

If you send a message for chat, no, of course, but is it for a command test the command against a array of commands you have expected and, if matchs, there´s a correct command.

Ah, you have just identified the core difference between TCP and UDP!

I might suggest you do a hash of the content or some form of checksum (add the value of each letter sent, etc) and have the receiving machine do the same thing with the content it recieved. The receiving machine can send back the hash/checksum value and the originating machine can verify if it is good.
