I have been expirimenting with sending messages to the User Messages box in the Driver Station, but it seems that there is a length limit. After about 15 characters, it will cut a bit of the 16th off, and not print any more. Is there a way to fix this? This is in the middle of the box, not the end so it is strange.
It should support 21 characters. It might help if you posted the code you are using.
I have successfully got 21 characters on the UM section. (with this code: http://www.chiefdelphi.com/forums/showthread.php?p=888700)
