Using AT Commands
. Result : OK- For valid parameters
- ATSr=n : Writing to S Resisters
Writes the n value in a register specified by „r‟. Registers such as S1, S13~S15, S17, S20~S24,
and S27 cannot be written by this command.
. Parameter : r = 0 ~ 99, n = 0 ~ 255
. Refer to the S registers.
- ATVn : Result Code Form
Decides whether to make the result transmitted to the DTE in a long or short form.
In case of the long form, you should carry out the <CR> and <LF>. However, in case of the
short form, you should carry out the <CR> only.
. Parameter : 0,1
. Default : 1
V0 : Delivers the result code in a short form<number>.
V1 : Delivers the result code in a long form<word>.
- ATWn : Negotiation Progress Reporting
This command enables the negotiation progress of the error-correction mode to be output. By
outputting it, the carrier speed and an error correction protocol are displayed in decimal
numbers and characters, for example, 77 and protocol: LAPM means that the error correction
protocol is LAPM. (Refer to the ATXn).
If it passes the error correction link and the connection is made, the CONNECT
XXXX message is output.
. Parameter : 0, 1
. Default : 0
W0 : Does not output the error-correction call progressing.
W1 : Outputs the error-correction call progressing.
. CONNECT XXX : The result code outputs the DEC speed.
- ATXn : Extended Result Code
The modem decides whether to respond to a dial tone or busy tone as well as defining how it
can handle the result code of the CONNECT message.
Waits for the time (default 5 seconds) specified by the S6 register, and performs dialing
