Re: [Freedos-user] USB to serial adapters and soundcard emulation on FreeDOS

2015-01-12 Thread Eric Auer

(forwarding from Guillem)

In response to Eric, I have tried DOSemu and I did manage to get the
serial ports to work. I had a few problems with it, though. Neither the
PC speaker or the Sound Blaster worked. To be honest I’m not sure if the
netbook I was running it on has a PC speaker anyways.
Another one of my problems with DOSemu is that, for some reason, when i
tried to use my DOS screenreader's review mode, the either the emulator
or the reader crashed. I can’t get out of review mode and my only way
out is by exiting the emulator. I could of course use terminal or dumb
mode but those don’t like some of the games I’ve tried, such as Eamon
Deluxe.
My most stable alternative right now is my Windows 3.1 VMWare virtual
machine, which actually works pretty well both in DOS and Windows mode,
except for the sound blaster which only works inside Windows. I might
postpone the dualboot until a better alternative is available since I
don’t think I’ll purchase a new laptop just for this.

Thank you.

 Hi Guillem,
 
 for another solution of your screen reader problem, you could
 use Linux (for which free screen readers and Braille drivers,
 both serial and USB are available) and run your old DOS tools
 in Dosemu or Dosbox inside Linux. That will emulate a classic
 Sound Blaster for DOS, no matter what your actual hardware is
 using for the sound. Would that be an option for you?
 
 Regards, Eric

Hi Guillem,

 In response to Eric, I have tried DOSemu and I did manage to get the
 serial ports to work. I had a few problems with it, though. Neither the
 PC speaker or the Sound Blaster worked. To be honest I’m not sure if the
 netbook I was running it on has a PC speaker anyways.

Normally, Dosemu uses the soundcard of your PC, not the
built-in speaker, and emulates a Sound Blaster for DOS.

 Another one of my problems with DOSemu is that, for some reason, when i
 tried to use my DOS screenreader's review mode, the either the emulator
 or the reader crashed. I can’t get out of review mode and my only way
 out is by exiting the emulator. I could of course use terminal or dumb
 mode but those don’t like some of the games I’ve tried, such as Eamon
 Deluxe.

My suggestion was to use not a screen reader for DOS, but
to use a screen reader for Linux. When you then run a DOS
game in dosemu, the screen reader should be able to read
that, too. It can help to use the text-only mode of dosemu,
which is admittedly less cool than the graphical xdosemu.

 My most stable alternative right now is my Windows 3.1 VMWare virtual
 machine, which actually works pretty well both in DOS and Windows mode,

Interesting idea!

 except for the sound blaster which only works inside Windows. I might
 postpone the dualboot until a better alternative is available since I

The so-called Sound Blaster PCI and Sound Blaster Live came
with their own DOS software which emulates a Sound Blaster:
Despite the name, those PCI sound cards actually have more
AC97 style hardware, so their DOS support only works through
their DOS TSR driver which seems to work quite okay once
you get it to work... Of course this does not help you for
a laptop, as you cannot exchange the soundcard there. Also,
I am not aware of DOS SoundBlaster emulation drivers for USB
sound sticks. Beyond the suggested dosemu and dosbox trick.

Regards, Eric
