Introduction
Internal constants
This page describes all the configuration language objects for Modem communication that can be displayed by the application program.
The following table describes the internal constants:
Object
%KWxy.i.0
%KWxy.i.1

%KWxy.i.3
Function
Type
Speed / format
Timeout
Slave address
Meaning

Byte 1: format z z z z x8: bit number (1 = 8 bits, 0 = 7 bits) x9 = 1: parity management x10: Parity type (1 = odd, 0 = even) x11: stop bit (1 = 1 bit, 0 = 2 bits)
Value of timeout
Byte 0: standard slave address
Byte 1: number of consecutive addresses
(from 1 to 3)

RTS/CTS delay Value of delay in hundredths of a millisecond
%KWxy.i.6
Speed / Format in ASCII mode
Byte 0 = speed in ASCII mode z 16#00 = 1200 bits/s, ...,16#03 = 9600 bits/s z z z z
Byte 1: format in ASCII mode x8: bit number (1 = 8 bits, 0 = 7 bits) x9 = 1: parity management x10: Parity type (1 = odd, 0 = even) x11: stop bit (1 = 1 bit, 0 = 2 bits)
%KWxy.i.7
Stop Bits received Byte 0 z z x0 = 1: end character enabled x1 = 1: end character included
Byte 1: value of frame end character
