3.9
The 2363's serial interface is factory set to operate at 9600 baud, with 8 data
bits, 1 stop bit and no parity. For user convenience, serial commands that
change the UART or Network settings do not take affect until the next
power turn-on or until a *RST, *RCL 0, or SYST:COMM:SER:UPdate
command is received. To change the serial settings, send the 2363 the new
serial parameters, verify them by querying the unit and then save the
configuration with the *SAV 0 command. Turn power off and back on or
use the *RCL 0 or SYST:COMM:SER:UPdate command to update the
UART.
NOTE: You must change the controller's serial settings
before sending the 2363 the next command.

3.9.1
The 2363 provides echos and prompts on its RS-232 interface. The 2363
defaults to echo on at power turn-on for keyboard operation. The echo
function can be disabled for computer operation by sending the unit a
CNTL-F. A CNTL-E turns the echo function on.
For terminal operation, use CNTL-E to turn echo on. If echo is on, the unit
will echo back the command or query, output a response if one is required
and a prompt.
For program operation, use CNTL-F as the first command to turn echo off.
The unit will respond to a command by returning a response if one is called
for and a prompt when ready for the next command. The user's program
should check and wait for the expected response and then the prompt before
sending the unit another command. The following examples show the unit's
response to user commands in bold type. The prompt formats are:
