LRC CHK (01) above is the error checking code. It can be calculated by means of the
instruction LRC. (8-bit mode: SM606 is ON.)
LRC check code: 16#01+16#03+16#21+16#01+16#00+16#06=16#2C
The two's complement of 16#2C is 16#D4. 'D' (16#44) is stored in the low
8-bit in D113, and '4' (16#34) is stored in the low 8-bit in D114.
Additional remark:
1. The format of the communication data in the ASCII mode:
