Telnet
Turns the iPocket232 into either a telnet client (most common use)
or a telnet server and allows the user to telnet out of the iPocket232
to a remote server, such as a UNIX workstation.
The standard connection control options are supported. By leaving
the Connection Control parameter at Automatic (default setting), the
user can initiate the telnet session by pressing any alphanumeric key.
If the Connection Control parameter is set to DTR/DSR Control, the
iPocket232 tries to open a telnet session as soon as DSR is detected
from the terminal, but the timeout function of most hosts makes this
option somewhat unreliable.
Telnet-Client: The most common use of the telnet protocol. To cre-
ate a telnet client, select tcp-client as the session mode. This con-
figuration allows the iPocket232 to communicate with the telnet
server at the configured Remote IP address and Remote Port.
Telnet-Server: To create a telnet server, select tcp-server as the
session mode when configuring this protocol. The iPocket232 lis-
tens on port 23, and the Remote Password must be disabled so that
the standard configuration program is not listening on that port. You
can configure Telnet to listen on a port other than 23 (but above
1024 to avoid using reserved ports).
Transpar-
ent
Typical setting. No alterations are made to the data stream, nor is it
parsed in any way. Data is collected until either the preferred packet
size is reached or there is a pause between characters that exceeds
the inter-character timer. The buffer is then transmitted as a single
frame. Preferred Packet Size and Max Inter-Char Delay can be left
at the default settings (0), and the unit will automatically determine
a reasonable setting based on the current serial port speed.
Transparent protocol includes the option “Packet Prefix”, which
allows you to include a header in the packet defining it’s length. See
Section 4.11, Packet Prefix (Transparent Protocol Only)‚ on
page 34.
