The default settings are Baud Rate: 9,600 bps, Start Bits: 1 bit, Data Length: 7 bits, Parity: Even parity
and Stop Bits: 2 bits.
Send Data Setting
Break the character string '@READ' into individual characters and store the character codes as array
elements in SendDat[].
In other words, BYTE#16#40(@) is stored in SendDat[0] and BYTE#16#52(R) in SendDat[1]. This pro-
cessing uses the StringToAry instruction.
