It appears that the Placer-400 is manufactured by Trimble Navigation, a
well-known GPS manufacturer.

Does your GPS say "Trimble" on it anywhere?  Or, for that matter,
"Sveesix"?  Trimble has a web page for what I presume to be a newer model,
the Placer 450: http://www.trimble.com/placer450455.html .

The "Trimble ASCII Interface Protocol" sounds like it's what you need to
research in order to be able to talk to the GPS.  A search turns up lots
of links, including a protocal specification at
www.agp.ru/oem/download/genf/taip.pdf and the directory
http://www.agp.ru/oem/download/genf/ seems to have some other goodies as
well.  This should have all the information you need to write a simple
program to talk to the GPS.

Hope this helps.
