| Subject: | opening the parallel.device |
Has anyone been able to get the RKM example code for the
parallel.device
to actually open the parallel.device? Even when the parallel.device
has been removed from the exec device list, along with the
misc.resource
& ciaa.resource, the device still fails to open. It's my
understanding
that when the device open count is zero, there is no other task using
the device & you should be able to open the device. I'd hate to have
to use the hardware directly, since the device commands for reading
& writing insulate one's code from a lot of details. parallel.device
has not changed from V40.1 in OS3.1. Apparently, when the printer
uses the parallel port, printer.device is able to access
parallel.device
as well. (some programs open both & I can see them on the exec device
list). Is there some other resource that has to be available before
the parallel.device can be opened? Jim Steichen, jimbot@rconnect.com
