Ok, I have looked at several questions posted along these lines and thought
I would ask one myself to summarize.

I would like all infomration on PPP for dos machines. I know ka9q exists,
but I would like a packet driver that I can use with other software. I have
looked at a ppp packet driver from merit.edu, but it seems to be setup to
log into merit nodes, not a general ppp setup.
I want to run Desqview X over my 19.2 Kbaud serial line for a few
applications.

On another note, which of the freeware ( I think that is as close to a
description as I can get ) PPP implimentaions for UNIX machines is best?
I am setting up PPP for several of our professors here, and would like to
know which one to use. The hardware is Sun4/110's and Sun IPC's, with
generic modems. I am looking for ease of installation and reliability.
Also, will PPP handle NFS traffic over the link? Well I have taken up
enough bandwith, responses by email will be summarized. Thanks for
everyones time.

If you find this, please post where you got it :-)

I use ppp-sparc4.1.1 and I like it a lot.  I have a Telebit t2500 talking 
to a t3000 hooked to a Telebit Netblazer (Dialup Router).

You can use NFS over the link.  It is slow and you do have to "tune it."
In my application (SS1+ t2500 - t3000 Netblazer), I had to tune NFS
like this:
host:/home /home nfs rw,hard,rsize=4096,wsize=4096,timeo=150 0 0

The timeout of 15 seconds and the reduced read size/write size make it
usable to a degree (~1.3-1.6Kbytes/second compared to 1.8Kbytes/s for
rcp -- a limitation of the 19.2Kbps I locked the serial port to).  I had
to do things via NFS since I have a data file on the host that controls
an application I use.  It works well, considering the slow speed.  As far
as tunign NFS for the slow links, I would highly recommend the O'Reilly
book "Managing NFS and NIS."  It has a performance section which 
helps immensely.
