You are prompted to enter one item from each column to configure the port, as shown
below.
Port configuration is made up of the several different parameters:
Bit Rate Data Width Error Detect Framing Flow Control
~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~
A. 300 8. 8 bits N. no parity 1. 1 stop bit N. none
B. 600 7. 7 bits O. odd parity 2. 2 stop bits H. h/w (rts/cts)
C. 1200 9. 9 bits E. even parity S. s/w (xon/xoff)
D. 2400 M. mark parity
E. 4800 S. space parity
F. 9600
G. 19200
H. 38400
I. 57600
J. 115200

Serial ports communicate using the RS-232 serial (bit-stream) protocol. Each byte
of data transferred through the serial port consists of a predetermined number of bits: 1
start bit, 7, 8, or 9 data bits, 1 or no parity bit, and 1 or 2 stop bits, for a total between 9
and 13 bits. The port configuration “8E2”, for example, results in a 12-bit data length
consisting of 1 start bit + 8 data bits + 1 parity bit + 2 stop bits. Serial ports on the
iPocket 232, however, support only 10- and 11-bit transfers. Port configurations of 9, 12,
or 13 bits are automatically converted by adding an extra stop bit to 9-bit transfers, and
dropping stop bits and parity bits (if necessary) from 12- and 13-bit transfers.
4.3 Connection Control
Connection Control specifies the method of connection between the iPocket 232 and the
remote serial device. The options are described in Table 4.4 .
Table 4.4: Connection Control Options
Option Description
Automatic Default
Useful for most setups. Initiates a connection as soon as there is
data to send (except in
tcp-server
mode).
