TSLIB and Serial Port Touch Screen

[Sidii]

Hi All,
Just want to know whether this is possible or not?

1. I have a serial port touch screen which is present at /dev/ttyS1
2. I have cross compiled tslib. Transferred tools like ts_test and ts_calibrate to the actual embedded device.
3. After running them, i do not get any output.
4. Environment variables are shown below:
   @
   export QT_QPA_PLATFORM=linuxfb
   export QT_PLUGIN_PATH=/home/Sid/plugins/generic
   export QT_QPA_GENERIC_PLUGINS=tslib
   export QT_QPA_FONTDIR=/home/Sid/fonts
   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/Sid
   export TSLIB_FBDEVICE=/dev/fb0
   export TSLIB_TSDEVICE=/dev/ttyS1
   export TSLIB_PLUGINDIR=/home/Sid/tslib_plugins
   export TSLIB_CONFFILE=/home/Sid/ts.conf

Am i missing something? Please let me know if tslib works for serial port devices or not?

Thanks.
