I used the Greenleaf library in a DOS application a number of years ago.  It
was quite a comprehensive package, though I did find a somewhat sticky bug.
(I think involving flow control.)  Though it took a while to resolve, they
were pretty good at responding to my queries, and got better at that over
time.

If you need really high performance (high baud rates, etc.,) you may want to
write your own driver, or optimize theirs.  For convenient use where
high speed (and this is relative to the system performance of your target
platform) is not at issue -- particularly if they have a working windows
driver -- it seems the preferred way to go.

I have had very good results with GreenLeaf's CommLib as well.  It's a
pretty solid package, and beats the pants off all the shareware
commlibs I tried.  (About 4 or 5.)

I got the CommLib from Austin Code Works.  I also recently ordered their
"CrunchPack" package, which, IMHO, is a piece of crap.  It comes on 5 360k
disks, and is a collection of shareware, freeware, and unknown ware
stuff that they hobbled together and sold me for thirty bucks.  (Dollars 
US to you non-US types.)  Most of it is available on simtel.  Most of
it has source, but most of it wouldn't compile without errors under 
BCC++ 2.0 either.  In some cases, even the executables wouldn't run on my
386/20 PC under DOS 3.3.  One program was just a big blob of Cobol source.
Almost none of it is anywhere near portable.  

It even contains UNZIP303, which forbids use in any commercial product.

Anyway, if you are looking for good portable compression stuff, do NOT
get Austin Code Works' CrunchPack.
 
If you just want to piddle over some code you could get free elsewhere,
but don't want to go to the trouble, maybe the crunchpack is for you.

*** CrunchPack is an Austing Code Works product, NOT a Greenleaf product.
    I couldn't be happier with GreenLeaf.

Ditto.
