PC/NFS, and how else can I get files from the *ix box?

[Laird P. Broadfield]

I've seen some discussion in the recent past about PC/NFS (but, of
course, I didn't know *then* that I was interested....)

Can somebody point me at sources for s/w?  I'd also appreciate comments
on use, and suggestions.

Actually; I'm not sure that's the best solution, so I'm interested in
what other suggestions anybody might have:  the goal is to periodically
(let's say half-hourly) read-access files on a unix box from a MSDOS pc.
Personally, my inclination is to just dialog through a serial tty port,
but (for assorted reasons) no serial ports are available, only an 
ethernet connection.

Suggestions, please?
