I solved this issue only recently in dosemu-1.1.3.3 and later. EMMXXXX0 is
the name of the device, however previous dosemu's did not recognize it as
a device name.
In earlier versions you could quickly hack around the issue by adding
EMMXXX0 to the list of reserved names ("CON", "AUX" etc) in
src/dosext/mfs/mangle.c. The newest DOSEMU's walk the DOS device driver
chain to find out which names correspond to devices which is a better way
to do this IMHO.
