Can anyone tell me how to read and write to a device file such
/dev/tty0p0 for example? This device is a touch panel. I am able to
write to it by simply opening the file and writing to it but I cannot
seem to read from it. The file seems to always be an empty file even
after I've written to it.
I am communicating with the touch panel through a standard RS-232 cable
on an HP workstation.
