Home Page
This ActiveX control can be used to
manually
manipulate the hardware handshaking lines of a serial communications
port.
To do this, follow the following steps.
-
Set the state of the control line
before the
port is opened.
-
Open the port.
-
Then assert the control line to the
state
you wish.
RTS Example:
-
IO1.SerialRTSControl(1) 'or 0 see
SerialRTSControl
documentation at main web page "Functions"
-
IO1.Open("COM2:", "baud=9600 parity=N
data=8
stop=1")
-
IO1.SerialRTSControl(5) 'or 6 to
change RTS
state as desired.
See Functions
for other handshaking lines.
