OnTermNotSignedIn
Data passed: terminal
Event: A command has been sent to a terminal that is not
signed in.
OnTermSequenceError
Data passed: terminal
Event: The one-for-one host prompt/terminal response
protocol has been violated. The host cannot send a
second Input command until it has received a response
from the first Input command. If WD802Term
receives 5 sequence errors in a row, a Host Logic error
is generated and the server shuts itself down.
While WD802Term/ActiveX will intercept and prevent most logic
errors, they are still possible so you should implement this event
handler!
OnTermIllegalCommand
Data passed: terminal
Event: An illegal command has been sent to a terminal.
WD802Term /ActiveX is designed to prevent illegal commands but
software is not always perfect and we may not have imagined all
the ways in which our customers will want to use it!
OnTermUpArrow
Data passed: terminal
Event: The up-arrow button has been pressed on a
terminal. You must issue another Input method call
before WD802Term can respond to another
keypress on the terminal. If you have already
entered some data on the terminal and press an
arrow key, this event will not fire.
OnTermDownArrow
Data passed: terminal
Event: The down-arrow button has been pressed on a
terminal. You must issue another Input method call
before WD802Term can respond to another
keypress on the terminal. If you have already
entered some data on the terminal and press an
arrow key, this event will not fire.
