Start code setting:
A setting of 1 enables the start code in 164
bits 8 to 15.

2: CR+LF
Default: 0
End code setting:
With a setting of 0, the amount of data being
received must be specified. A setting of 1
enables the end code in bits 0 to 7 of 164. A
setting of 2 enables an end code of CR+LF.
0 to 7 00: 256 bytes
01 to FF:
1 to 255 bytes
Default: 00
Set the data length to be sent and received
with no-protocol communications. The end
code and start code are not included in the
data length.
Set this value only when the end code set-
ting in bits 8 to 11 of 165 is “0: None.”
This setting can be used to change the
amount of data that can be transferred at
one time by TXD(236) or RXD(235). The
default setting is the maximum value of 256
bytes.
