Configuration
Serial Channel (Port) Configuration
7-15
If “Send Immediately After Characters” is not set, any characters already in the serial
buffer are included in the transmission after a “transmit” condition is found. If set, the
Device Server sends immediately after recognizing the transmit condition (Sendchar or
time-out).
Note:
A transmission might occur if status information needs to be
exchanged or an acknowledgment needs to be sent.
Inactivity (Disconnect) Time-out
Use this parameter to set an inactivity time-out. The connection is dropped if there is no
activity on the serial line before the set time expires. Enter time in the following format:
mm:ss, where “m” is the number of minutes and “s” is the number of seconds. To disable
the inactivity time-out, enter 00:00.
Send Characters
You can enter up to two characters in hexadecimal representation in the parameters
“sendchar.” If a character received on the serial line matches one of these characters, it is
sent immediately, along with any awaiting characters, to the TCP connection. This
minimizes the response time for specific protocol characters on the serial line (for example,
ETX, EOT, etc.). Setting the first sendchar to 00 disables the recognition of the characters.
Alternatively, the two characters can be interpreted as a sequence (see Pack Control on
page 7-14).
Telnet Terminal Type
This parameter appears only if the terminal type option is enabled in Disconnect Mode (see
Disconnect Mode on page 7-12). If set, you can use the terminal name for the Telnet
terminal type. Enter only one name.
If the terminal type option is enabled, the Device Server also reacts to the EOR (end of
record) and binary options, which can be used for applications like terminal emulation to
IBM hosts.
Note:
The telnet terminal type password and the channel (port) password
cannot be active at the same time.
Channel (Port) Password
This parameter appears only if the channel (port) password option is enabled in Disconnect
Mode (Disconnect Mode on page 7-12). If set, you can set a password for the serial port.
The maximum length of the password is 16.
Note:
The Telnet terminal type password and the channel (port) password
cannot be active at the same time.
