Baud etc should be variable, etc you can pick some defaults but they should be set in the program and possibly stored in a config file.

I believe the other GPS units they use have no comm interface, so they will manually enter the info.

It does matter, since not all GPS units use the same settings for for baud rate, data bits, parity, stop bits and handshake. Although the NMEA 0183 standard is common, it is by no means the only standard that GPS units use.

Since they have both differential (big, expensive "professional" type units) and handheld ("consumer grade" units), it is possible that they use more than one standard.

I will send them an email tonight, just to be sure.



PS. I will upload my first attempt at serial comms in C# in a minute..... getting there, but not finished yet! If i've done anything thats a bit weird/not good in C# feel free to point it out!!
