Clipper 5.3 program under dosemu

[Bartos-Elekes Zsolt]

Hi!

I have to set up a dosemu environment for a clipper 5.3 program, using the 
DOS/16M dos extender. The problem is that the program can't use the memory 
above 1 MB. According to the docs, the program SHOULD use DPMI, and the logs 
show that it is actually doing some DPMI calls (GetFreeMem, Alloc, etc), but 
it is not using as much memory as DPMI offers.

Here are my memory settings:

$_xms = (16384)         # in Kbyte
$_ems = (off)           # in Kbyte (couldn't make the program use it)
$_ems_frame = (0xE000)
$_dpmi = (16384)        # in Kbyte
$_dosmem = (640)        # in Kbyte, <= 640
I have a simple Clipper program that displays the memory available to the 
program (251k gzippped), I can email to anyone willing to debug a little.

Other programs using DPMI (like Turbo Pascal 7.0's tpx.exe) are seeing and 
using correctly all DPMI memory available.

My system configuration:

Celeron 366, 128 MB RAM, ~100 MB swap
Debian 3.0r1
dosemu 1.1.5, compiled from sources
compiletime-settings:
config {
  experimental off
  sbemu off
  mitshm off
  vidmode off
  x off
  net off
  dodebug off
  linkstatic off
  cpuemu off
  aspi off

  plugin_extra_charsets off
  plugin_term off
  plugin_slang off
  plugin_translate off
  plugin_coopthreads on
  plugin_commands on
  plugin_demo off
  target_cpu auto
  prefix /usr/local
  bindir ${prefix}/bin
  sysconfdir /etc/dosemu
  datadir ${prefix}/share
  mandir ${prefix}/man
  docdir ${datadir}/doc/dosemu
  syshdimagedir /var/lib/dosemu
  x11fontdir ${datadir}/dosemu/Xfonts
  fdtarball none
}
Clipper version 5.3b Intl. (338)
DOS/16M version 6.01
Can anyone help me?

Thanks,
Zsolt
