This shouldn’t (heh, heh) happen in the Rivendell code, as the routines to process RML as well as the switcher drivers themselves are single-threaded. I suspect that what may be happening is that the serial command buffer in the 16.4 itself is overflowing when two commands are sent in quick succession. I’ve seen this happen at other sites with that particular model. The work-around was to reduce the baud rate of the serial connection, which seemed to settle things down.
