[comp.os.msdos.programmer] Searching for pre-emptive multitaskers

Hi,

  I've been asked to port a protocol to a DOS machine.  The 
  requirements of the system include simultaneous upload/
  download/printing/database queries... 

  I thought that the best way around this would be to locate
  a pre-emptive multitasker.  I came across "CTask22" on 
  "wuarchive", and was wondering if someone could comment on it.

  In additional, are there other packages out there (public
  domain and/or commercial).  

  Thanks in advance.

Ctask 2.2 has lots of satisfied users, with lots of nontrivial
applications.  I can report a problem or two (Thomas Wagner: this
is NOT a complaint!)

I've experienced having the PC choke when a Ctask22 application,
which is a TSR, does disk I/O at the same time as another TSR.
Another user reported a similar problem, except his "other TSR"
was a network server of some obscure type.

For plain-Jane cooperating subtasks, it is great however.
No Windows support - yet - but Thomas is known to be looking
at the problem.
