Date: Thu, 26 Apr 2001 10:46:23 +0200 From: Alexander Pipelka <pipelka@bms-austria.com> 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).
