http://bugs.winehq.org/show_bug.cgi?id=58594 --- Comment #1 from Janne <janne.kekkonen(a)gmail.com> --- Created attachment 79130 --> http://bugs.winehq.org/attachment.cgi?id=79130 script that writes to serialport It seems to be possible to reproduce issue with virtual serial port. I created two virtual ports with command: socat -d -d pty,raw,echo=0 pty,raw,echo=0 I added COM3 as dev/pts/2 to wine registry. Opened com3 with teraterm and used script to write to port /dev/pts/1 with 1 second interval. While script is running GUI is somewhat sluggish and data is seen on terminal with 1-3s intervals. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
