set ports
Chapter 2 Command Descriptions 173
flushstchar={default|on|off}
Determines whether the first character of an autoconnection is discarded.
If you specify "flushstchar=default," the first character will be discarded
for Telnet and Rlogin connections and will not be discarded for raw
connections.
group={none|group}
Assigns a group number to this port, which means that this port is part of
a hunt group. Outgoing calls specifying this hunt group can then use any
available port in the group. Use numbers that will not cause conflicts with
regular port numbers. For example, on a four-port device, use numbers
5 to 99. The default is "none."
id={id name|none}
Specifies a character string for the port, which can be used in console
management applications to identify the device connected to the port. If
there are spaces in the string, enclose this string in quotation marks.
idletime=0-60000
This option allows users to override how and when serial data received
is sent over the network. The value is in milliseconds.
If set to 0, then Digi’s standard algorithm is used; which is designed to
lower data latency by sending smaller packets more frequently.
If set from 1 to 60000, then the serial port driver waits for at least the
configured milliseconds with no more data received before sending the
data on the network. This increases the probability (but does not
guarantee) complete serial messages get sent as a single network
packet.
The buffered data is always processed when it reaches the defined
maximum, which defaults to 1024 bytes (1K).
There are several caveats to using this timeout option:
• Setting this option to a non-zero value adds to CPU load, so only
use if required.
• Setting this option adds the value set (that is, the milliseconds
specified in the 1-60000 range) plus an extra 1 to 2 milliseconds to
every serial response due to the measuring of this idle time. As a
result, a setting of 1 millisecond can cause a 7- or 8-millisecond
latency, not 1 millisecond. The actual latency varies by product and
the number of serial ports involved. That is, the added latency for a
Digi One SP will differ from a PortServer TS 16.
keepalive={on|off}
Determines whether the keep-alive function is implemented with
autoconnections. The default is "off."
nlines=0-10
The number of lines of serial data to be displayed at a time.
