[Elecraft] K3 programming problem

[n5ge at n5ge.com]

I don't have a Unix system, so can't speak Unix to you but in my personal
application written in C# I do this:
					
do
{
	byteRead = (byte)serialPort.ReadByte();
	byteBuffer[bufferedByteCount++] = byteRead;
	s = Encoding.ASCII.GetString(byteBuffer, bufferedByteCount - 1, 1);
} while (s != ";");
