Maple Systems STEPware-100 - Manual (Page 31)

In all three modes, the line terminator is sent to the host controller when the OIT
responds to a control command and when the OIT’s ENTER key is pressed.
In Interactive mode, if local echo is enabled when the OIT’s ENTER key is pressed, the
line terminator is also sent to the OIT’s display.
In Block or Network mode, if block echo is enabled when the OIT’s ENTER key is
pressed, the line terminator is also sent to the OIT’s display.
In Network mode, the line terminator is used to indicate that the host controller has
finished communicating to a particular OIT. The line terminator, therefore, notifies the
other terminals that the next two bytes received from the host controller indicate which
OIT the host controller wants to talk to.
Refer to Chapter 3: Operating Modes for more information on the use of the line
terminator in Interactive, Block, and Network modes.
To modify this parameter using STEPware-100:
1. Open the Configuration Editor.
2. In the OIT Operational Settings group box, select the desired line terminator from the
Line Terminator option buttons.
To modify this parameter in Configuration mode:
1. At Line Term:, use the OIT’s TOGGLE key to select the desired line terminator. Refer
to the Configuration Mode section in this chapter for more information.
To modify this parameter from the host controller:
1. Use the Set Line Terminator control command. Refer to Appendix A: Control
Commands for more information.
Append Linefeed Setting
This parameter determines whether a linefeed LF control character (0x0A) will be
appended to any carriage return CR control character (0x0D) that is sent to the OIT from
the host controller. If enabled, this will cause the cursor of the OIT display to move
down to the next line of the display when a CR is received from the host. This feature is
useful when using controllers which can send ASCII strings followed by a CR control
character but are unable to append the LF control character to any ASCII string sent.
Without sending a LF control character, the host is forced to display characters on the
OIT screen on one line of the display only. This feature allows any host that is unable to
send the LF control character to use all of the lines of the OIT display.
To modify this parameter using STEPware-100:
1. Open the Configuration Editor.
2. In the OIT Operational Settings group box, select the Append Line Feed check box.
To modify this parameter in Configuration mode:
1. At Append LF:, use the OIT’s TOGGLE key to enable or disable the Append Line
Feed feature. Refer to the Configuration Mode section in this chapter for more
information.
To modify this parameter from the host controller:
1. This feature cannot be changed from the host controller.
