4.3 Terminal Software Setup for Memory Register Control
Communication or terminal software is necessary to set the memory registers. Nearly any
PC communication software can be used. Launch the communication software and set the
terminal’s communication parameters as shown below. Refer to your specific
communication software instructions how to set these parameters.
bit rate: 9600 bps
data length: 8 bits
stop bits: 1 bit
parity bit: none
flow control: none
local echo: yes
terminator: carriage return + line feed
4.4 Memory Register Setting
Memory registers set the operation mode and communication parameters of the modem
and retain them in memory. All of the settings of the modem are made by these memory
registers.
Since the memory register is based on rewritable non volatile memories, these memories
can be readily rewritten by external terminal equipment such as PC and their contents will
be kept even after the power is turned off. This non volatile memory can be rewritten about
1 million times.
4.4.1 Memory Register Referencing and Setting
Memory registers are referenced and set with the REG command. (For more information,
refer to REG section at p.43 C
OMMAND S ET D ESCRIPTION )
Example procedure:
1. To view the current value of register 00, enter:
@ REG00 CR/LF
2. Modem responds with 00H CR/LF (REG00 is assumed to be 00H in this case and
varies in each setting case)
3. To set register REG00 to 0FH, enter:
@ REG00:0FH CR/LF
4. Modem responds with “P0”
CR/LF
5. Enter “
@ RST CR/LF ” or cycle the modem power, to activate new values
@ = command header (specify following characters are command)
CR/LF = Terminator (carriage return + line feed)
When rewriting the modem’s memory registers, do not turn the
modem’s power off until the modem returns “P0” response. If the
power is interrupted before “P0” is returned, the memory contents
may be lost or corrupted and the modem operation will be
unpredictable.
