>I am aware that DOS is not multitasking but as a user it doesn't make
sense to use a browser that I have to keep looking at the same page
while making a download during half an hour or so.
A sort of double tasking could be implemented inside Arachne that could
divide time (80% for downloading, and 20% for browsing or so, every second
or so ) and this would make mostly everybody including myself, happy about
using Arachne for a more than 5 minute download. Windows use similar
scheme for splitting time among tasks. Some cellular phones use it too.
It is called Time Division Multiplexing.

I have tried to do other things while downloading, especially a Web page, and
found I could do essentially nothing, that everything else was reduced to a
crawl. That was with OS/2 Warp 4, a multitasking OS. Only exception was when
the Web page download was stuck and doing nothing, then I could switch to
another task. I have Cx486DX2 at 66 MHz. Maybe a fast Pentium or Athlon could
multitask better under such circumstances? If I had a sound card and Real Audio
on this computer and were listening to a radio program via the Internet, I would
probably not be able to do anything else at the same time.

If you wanna to make Arachne multitasker/multithrtead prog you must
change from Borland C++ to DJGPP, and Arachne must make contain
a lot of os-like services, because bios and dos services can not be used.

Is that why DOS Internet applications are so tricky to get right? Other OSes
have the services available, while with DOS, they have to be re-created.
>Under plain dos you can use small progs as tsr's.
Ralf Brown developed a way you can have 255 tsr on one machine
in the same time and it will be compatible on all machines.

255 TSR on one machine may be theoretically possible, but fitting them all in
low memory is another story.
