Add support for accessing ports. This was done to access parallel

ports, but should work for others as well.

ELFize. In fact, doscmd is ELF natural -- there is no need for a loader

1998-09-24T01:11:45+00:00

since ELF executables are loaded well above the low memory region that
DOS operates in.

Change doscmd to use i386_set_ioperm() call instead of sysarch().

o for unknown int21 functions, set the CY bit to indicate failure

1998-07-17T00:18:52+00:00

o When reporting a int21 function we don't know about yet, report
  AH as the major and AL as the minor, as opposed to reporting AL
  as the major.
o Add support for 21:44:7: ioctl check output status.  We
  optimistically say that output is always ready.
o Add half support for 21:23: get file size.  We always now return
  failure.  This function isn't supported, according to the interrupt
  list, by the DOS box in windows, so I don't feel too bad.

o remove -f from doscmd man page, as it is not implemented.

1998-07-16T23:54:26+00:00

o Remove init printf
o Don't set optind from return value for do_args.  getopt has already
  done this.
o Bump EMS memory from 1M to 10M (this really should be a command line
  option).
o Open /dev/null when requested to open emmxxxx0 to allow many programs
  checking to see if EMS is installed to find it.
o Route int67 to ems_entry to allow EMS to be used when DOS is emulated
  as well as when DOS is booted.  This may obviate the need for the
  driver doing anything at all in a really booted situation and won't
  hurt that case.

I can now run the DOS program I'm interested in running with enough
EMS memory that its "advanced" functions are enabled and working.
