Murray-
After the ELO_MAX_WAIT fix, it seems to be working very well (can calibrate and
use the screen). I did notice that it seems to be unable to open the screen on
every other run of elotouch (getting "EloOpen tcsetattr: Operation not
permitted" and "Could not initialise touchscreen on port:
/tmp/SUNWut/sessions/11/unit/dev/term/a"). I also noticed that it exited 0 with
that error, so I made the following changes:
* In elotouch.c around line 75 (right after the "could not initialise" error is
printed), I added a "return 1;".
* In elotouch.c at the end, I changed the return for main to "return result;"
(so the return status from run_driver gets passed back out)
With these changes, I should be able to script around problems.
I've also noticed a "Checksum error on Elographics touchscreen link" after the
first touch, but it seems to have no effect.
Also, for your info, here is the ID printed by the program about my specific
setup:
Elographics touchscreen is a Intellitouch, connected through a serial link.
The controller is a model E271-2200, firmware revision 1.12.
Additional features:
External A/D converter
Z axis active
(odd thing is that the controller is really a 2701RSU - maybe it IDs
differently).
Overall, it looks great! It looks like I owe you a round..

Hi Jon / List
I've been able to get the 1.21 driver working in OEL 5.5 64bit after changing
ELO_MAX_WAIT in touchscreen.h
Change it from 100ms (100000) to 1000ms (1000000) and you should have success.
Please let me know how you go.

Hi Jon & SunRay-Users
I've corrected a small pointer problem, code now compiles and runs on 64 bit
Linux.
The new version is here, with changes to touchscreen.c and touchscreen.h
http://sourceforge.net/projects/elotouch/files/elotouch-1.2.1.tar.gz/download
I still can't get it to work correctly with the Sun Ray serial port redirection
on Linux. I'll do more testing on Monday but this seems to be the same issue
I've had before with Linux and serial port connection - seem to get corrupt
data.
If I connect a USB-serial adapter to the server, and open /dev/ttyUSB0 instead
of $UTDEVROOT/dev/term/a the driver seems to work fine.

Hello,
I'm currently trying to get an ELO touchscreen (with the 2701 controller via
serial) working on SRS5 running on OEL5. I did some research and saw the
elotouch ( http://sourceforge.net/projects/elotouch/ ) project mentioned on the
list before. Based on my reading, this seems like the perfect option.
Anyway, I compiled/installed the software, but can't seem to get it working.
It's falling over doing tcsetattr on the serial port.
I get one of two messages when trying to run it (elosetup -p
$UTDEVROOT/dev/term/a):
System error while reading from Elographics touchscreen.
...or...
EloOpen tcsetattr: Operation not permitted
Unable to configure Elographics touchscreen port
Has anyone else set up this package and had similar issues?
