There is software that works with the Oncore GPS series. Called
""SynTAC" It is Windows-only but it seems to run on my Linux system
under VMware Player. You can place the UT+ into survey mode and set
other parameters. It has a graphic Sat. display. The page says the
licensee expires in 30 days but but, it seems not to.
