So I >hacked the driver to just spin for a while sending characters when it There is already a good interruptless driver by Wolfgang Stanglmeier and Andy Valencia. Adrian Hall has built a kernel with the driver installed. It should be available via anon ftp at: rachel.ibmpcug.co.uk. Please try this driver if Eric Haug's lpt patches (or Terry's ?) from agate don't work. Let us (i.e., the net, or Nate Williams, the buglist maintainer) know if there are problems, along with any relevant information (like make of your i/o card...). Thank you. -Andrew Moore <alm@netcom.com>
