'A'= ASCII (default)
'E'= excess 3
'P'= packed BCD
'S'= Sandia G-822A fmt
x: x
'0' = Sandia single Mag
'1' = Sandia dual Mag
3: CR
carriage return
[Note: the '0' and '1' 3rd characters are valid only when selecting the
Sandia format. This format was developed for an earlier logging
software program and is now obsolete. Excess3 is used for high
speed multi-sensor array data transmissions.]
