4.1 Protocol
The Protocol setting defines how the iPocket232 communicates with the remote server.
The Protocol setting has two parts: data formatting and session mode.
The first part of the Protocol setting, data formatting, indicates how to parse or process
the data stream to provide compatibility with the remote server. Table 4.1 describes the
data formatting options.
Table 4.1: Data Formatting Options
Menu Item Description
Disabled Default setting. The unit will not accept any host initiated or local sessions.
You must choose a protocol for the unit to become active.
IMPORTANT! The iPocket232 is a DCE device and therefore cannot
remotely control the DRT and RTS signals, nor monitor the DSR, CTS, and
DCD signals in compliance with RFC2217. Port speed, parity, data width,
and handshaking all function correctly.
Extends a serial link to allow remote configuration and control of a
serial port. Upon receipt of a message containing Com Port Control
commands, the iPocket232 extracts the command information from the
message and sets the following parameters of the serial port: baud rate,
data length, parity bits, stop bits, DSR signal, and flow control.
Once the serial port is set, the iPocket232 forwards the data to the serial
device unchanged. If any changes to the Com Port or modem line occur,
the iPocket232 will automatically send a notification packet to the host.
Once the transaction/transmission is complete, the iPocket232
automatically resets to the Port Setting defined in the Serial Port
Settings sub-menu until the next message is received.
Telnet Com Port Control is defined in RFC2217.
If you are connecting only one iPocket232 to a PC and the application
requires COM port connection, you can use Com Port Redirector
software if your application is not affected by the limitations noted
above. You can find more information and purchase this software on the
IPocket232 Web site at http://www.ipocket232.com/index.php/com-
