Subject: SDL ELO driver bugfix
Hi Sam!
We noticed that the ELO serial touchscreen controller is quite sensitive
in terms of correct protocol handling.
The current implementation cause some controllers to hangup after some
time (> 24h).
I think the attached patch should fix this (I ran my device more than 3
days without any hangups).
