Try writing directly to anything not supported by an OS/2 device driver,
¨such as a real midi card. Without the driver, OS/2 has no control over it
¨and allows direct access to the hardware, even in a VDM. I use a Roland
¨SCC-1 and Cakewalk for DOS. Do not have a driver loaded and this DOS
¨program reads and writes the ports directly. Throw in an OS/2 driver for
¨MPU-401 support and direct reads/writes get intercepted. Even in such
case, ¨OS/2 asks wether to ignore this or stop the process. As such, I
believe it ¨not only conceivable, but highly likly that someone could quite
easily ¨bypass any system driver. In any case, the moderator has already
seen fit ¨to threaten me with the loss of this echo (unfairly at that) so
this thread ¨must be dropped...
