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.

Default setting. The unit will not accept any host initiated or local
sessions. You must choose a protocol for the unit to become active.
ComPort
Control
IMPORTANT! The iPocket232 is a DCE device and therefore
cannot remotely control the DTR 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 auto-
matically resets to the Port Setting defined in the
Serial Port Set-
tings
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 applica-
tion requires COM port connection, you can use Com Port Redirec-
tor software if your application is not affected by the limitations
noted above. You can find more information and purchase this soft-
