Configuration Parameters
These features are available separately or in any combination. Each Model 5390 server requires a
unique key value for the feature(s) you choose; contact your supplier to obtain an option_key value.
output
_flow_control
This asynchronous port parameter defines the method that a device uses to stop output from the
Model 5390 server. Table C2-11 describes the valid options; the default is start/stop.
output_is_activity
This asynchronous port parameter defines activity as output. When enabled, the Model 5390 server
resets the inactivity timer when it sends output from the port. If the line type is hardwired, the

Parameter
Option Description
bell Comparable to setting the parameter to none.
eia Selects hardware flow control; eia works only if the
control_lines parameter is set to flow control or both and
the device is wired properly.
start/stop Specifies XON/XOFF flow control (independent of the
control_lines parameter). Upon receiving XOFF
(output_stop_char), the Model 5390 server stops sending
output to the device. After receiving XON
(output_start_char), the Model 5390 server starts sending
output to the device. The Model 5390 server removes these
characters from the data stream.
both Specifies both in-band (XON/XOFF) and out-of-band
(CTS/RTS) flow control (if control_lines is set to
flow_control or both). Both flow controls are independent;
data flows out of the port only if CTS is high and the last
received character was XON. Receiving XOFF or dropping
CTS stops output (Model 5390 to device) flow.
none Specifies no flow control; characters are lost if the buffers
overflow.
