Getting data in hyperterminal but not in ReadExisting

Question

Hello All,

I am able to view data coming in the serial port using HyperTerminal but it comes in as garbage in my C# program using the readExisting() method.  I am guessing that I have to convert the incoming data from ascii to text possibly?

I have connected a null modem serial cable from COM1 to COM2 and can type letters from HyperTerminal into my program but when I connect my program to the GPS device it comes in as nonsense but is readable in HyperTerminal.

Thank you in advance for your help.
