Re: [announce] dosemu-1.3.2

Hi all,
my name is David Cavazzini and I live Italy.
Several years ago I started to use dosemu, always with some troubles,
but it worked and it was usefull :-) : thanks to programmers.
I'm now asking you if redirection now works in dosemu with freedos or it
doesn't yet. So if is possible to use lredir.exe or emufs.sys other with
the MS-DOS or Caldera OpenDos
I'm still looking a way to use dos partitions in a freedos box without
unloading them from the linux fs prior, being able so to upgrade dbfiles
without stopping programs.
Someone experienced something similar?
Thanks in advance for your kind attention,
have a good evening
David
