In the Trimble units, anyway, there are several different modes. Writing
code to work in ASCII mode vs Binary wasn't all that difficult. The binary
mode offers a lot more capability, However, detecting which mode the unit is
in at startup and then switching modes proved a little tricky. The units I
worked with had a battery backup option and some had the settings programmed
into eeprom while others did not.
If you are dealing with NMEA (which offers less options), there are a few on
Delphipages and Torry's.
