Note: Depending upon your product type, this dialog may vary. This help context covers all possible configuration parameters. If your dialog does not contain certain parameters, they don't apply to the product you are configuring.
CTS/RTS Required
-
This option specifies whether or not a Clear To Send (CTS) or Request To Send (RTS) input signal can determine the port status
-
-
If enabled, this option performs one of two functions:
-
-
If the port is externally clocked, a CTS input signal identifies the port's status.
-
-
If the port is internally clocked, an RTS input signal identifies the port's status.
-
Range: Enabled or Disabled
-
DCD Required
-
This option specifies whether or not a Data Carrier Detect (DCD) signal can determine the port's status, providing the port is externally clocked.
-
This parameter does not apply to ports that are internally clocked because the port asserts DCD when it becomes active.
-
Range: Enabled or Disabled
-
DSR/DTR Required
-
This option specifies whether or not a Data Set Ready (DSR) or Data Terminal Ready (DTR) input signal can determine the port status.
-
If enabled, this option performs one of two functions
-
-
If the port is externally clocked, a DSR input signal indicates the port's status
-
-
If the port is internally clocked, a DTR input signal indicates the port's status
-
Range: Enabled or Disabled
-
Drive SCTE as Output
-
This parameter defines whether or not the port can use a Serial Clock Transmit External (SCTE) signal as input for a port emulating a DCE (internally clocked) device, or driven as output for a port emulating a DTE (externally clocked) device.
-
The Auto selection depends on the port's clocking:
-
-
If the port is internally clocked, this options is affected by the cable type and line speed:
-
-
For RS232, SCTE is not an available input
-
-
For V.35, running at less than 256 Kbps, SCTE is not an available input.
-
-
All other configurations can use SCTE as input.
-
-
If the port is externally clocked, the Auto option always uses SCTE as output.
-
Range: Yes, No, or Auto
