[lcd4linux] T6963 / corrupted output

[Christoph H. <e05...@st...>]

Hi all!
I recently bought a 128*64px t6963c based LCD. It works fine with the vendor
supplied Test program (Delphi source included in
http://www.pollin.de/shop/downloads/D120291S.ZIP) as well as with serdisplib
1.95 (so it works with lcd4linux if I use the serdisplib driver), but with
lcd4linux (CVS from 06.08.2005) and the T6963 driver I get only corrupted
output and a glibc free error message. Attached is the output of lcd4linux -F
-vvv :

===serdisplib (works), canceled with CTRL+C===

Pictures of the right/corrupted greeting msg/default layout output are
available at http://stud3.tuwien.ac.at/~e0525270/lcd4linux/ .
I would be thankful for any comment/attempt to solve this problem.
