5.3.12 $AATN[CrLfmode]

Description :
This function reads/sets what the characters are as judging the end of command or
response string.
$AATN [chk](CrLf)

Reads the setting value of CrLfmode stored in the
EEPROM.
$AATN(CrLfmode) [chk](CrLf)

Sets the setting value of CrLfmode for the
command/response string.

Syntax :
$AATN[CrLfmode][chk](CrLf)
$
Delimiter character
AA 2-character module address in HEX format. The valid range is from
00 to FF
N=0 Reads/Sets the CrLfmode value of the COM 2
N=1 Reads/Sets the CrLfmode value of the COM 1/3/4/5/6/7/8
(CrLfmode): 0

(CrLf)=0x0D (CR)
1

(CrLf)=0x0D+0x0A (CR+LF)
2

(CrLf)=0x0A (LF)
3

(CrLf)=0x0A+0x0D (LF+CR)
4

No end character
[chk] 2-character checksum. If the checksum is disabled

no [chk]
(CrLf) End Character

Response : valid command

!AA[CrLfmode][chk](CrLf)
invalid command

?AA[chk](CrLf)
no response

syntax error, communication error, or address error
! Delimiter character indicating a valid command
? Delimiter character indicating an invalid command
AA 2-character module address in HEX format
[chk] 2-character checksum. If the checksum is disabled

no [chk]
(CrLf) End Character

Example : (Assume the AA address value of the I-7523 module is 01)
command: $01T0(CrLf)
response: !014(CrLf)
command: $01T1(CrLf)
response: !011(CrLf)
command: $02T1(CrLf)
response: !022(CrLf)
The end char for COM2 is no end character
The end char for COM1 is 0x0D+0x0A
The end char for COM3 is 0x0A
