Blocking Read/Write messages

[ricardocrl]

Hi all,

Does anyone know if there is any programming language for the NXT that handles blocking functions for the mailboxes?

As far as I know, with NXC it's only possible to read and write to mailboxes with non-blocking functions. I looked a bit through the firmware some time ago, and LEGO standard firmware doesn't actually care about overwriting messages or check if something new is availabla or not. So I imagine that I need a different firmware.
