The latest version of PARIDE can be found in 2.0.35, but I don't think this
is something that upgrading is likely to address.

I suspect that you are getting I/O errors for one reason or another. Usually,
these errors cause a message to be displayed to your console, however, if
you are running X you won't see then.

Also, I'd like to know what mode the epat driver is using for your port.
It is possible, especially with some older unidirectional ports that you
need to increase the port delay setting.

So, please let me know what sort of computer it is (processor & speed),
whether you can set the parallel port mode, what mode it is in, and the
kernel log messages when you load the pcd driver. You can retrieve those
messages using the dmesg command, or possibly from your system's kernel
log file.

Then, please reproduce the problem you are having, and send me the first
two or three messages that appear on your console, once the problem sets

If it is not too much work, doing all this with the current version of
PARIDE would be appreciated.
