_OEM_CD
Name:
_OEM_CD
Syntax:
Any expression that can use a variable as part of its contents.
Description:
This variable is treated as a DIGITAL_INPUT and may be read from only. CD is the
acronym for Carrier Detect. When a modem is hooked up to an RS-232 port and a
connection (carrier) is made, the modem typically drives this pin high to let the
connected hardware know that a data connection is present. This line may be used for
other purposes depending on the hardware connected to the CEN-OEM.
Example:
PUSH _OEM_CD
{
PRINT(“Carrier Detect Pin has gone high!\n”);
}

_OEM_CTS
Name:
_OEM_CTS
Syntax:
Any expression that can use a variable as part of its contents.
Description:
This variable is treated as a DIGITAL_INPUT and may be read from only. CTS is
the acronym for Clear To Send. In flow control for handshaking, a device will
typically control this line, and raise it high when the CEN-OEM is allowed to
transmit, and drop it low when it wants the CEN-OEM to stop transmitting.
It can also be used in other situations besides flow control, and in these situations, the
CEN-OEM can monitor the status of the line directly through this pin.
