IIRC, the docs for PMCOM are in the form of info files, which are built
when you compile the package.  You will need to compile and install PMCOM
first then use `info' to read the docs.

Using a library is probably the easiest way.  It really depends how much
functionality you need and how much you want to modify your code.

Unless you use the Filesystem Extensions that Eli mentioned, you must go
through your code and replace all the instances of open, read, write,
etc. with calls to the comms library (or maybe use wrappers).  Of course,
that might be more or less effort than using FSEXT.

PMCom is a very comprehensive library.  Obviously a great deal of effort
has gone in to writing it, and the docs, but perhaps it's more than you
need.

SVAsync is a simple, yet still functional, library.  Plus all the docs
are in one text file, which should take < 10 minutes to digest.

There are others worth looking at (e.g. BCSerio), see the FAQ for a list.
