Depends on how it arrives at the sreail prot: if it arrives as a single byte, then just read that from the port, and set the TextBox.Text property:

C#

myTextBox.Text = myRecievedByte.ToString("X02");

If it arrives as a string of '0' and '1' characters then read the entire string and convert it first:

C#

byte myRecievedByte = Convert.ToByte(myRecievedString, 2);

C#

byte value = serialPort.ReadByte();
string hexString = value.ToString("x2");
