For example, using 12345 as the number to be dialed, it is normally accomplished through either the
ATDT12345 or ATDP12345 command. In the force pulse dialing mode of operation, the following string
should be issued:
If the result code is a “t”, the dialing was accomplished using DTMF dialing. If the result code is “tt”, the dialing
was accomplished using pulse dialing.
In the above example, the CC-2401 dials the first digit “1” using DTMF. The “,” is used to pause in order to
ensure that the central office has had time to accept the DTMF digit “1”. When the CC-2401 processes the “p”
command, it attempts to detect a dial tone. If a dial tone is detected, the DTMF digit “1” was not effective,
hence, the line does not support DTMF dialing. Conversely, if the dial tone is not detected, the DTMF digit “1”
was effective, and the line supports DTMF dialing. The character after the “p” may or may not be dialed
depending on whether the DTMF digit “1” was effective or not. If the “1” was effective, the character after the
“p” is skipped. The next DTMF digit to be dialed is “2”. Subsequent digits are all DTMF. If the “1” was not
effective, the first character after the “p” (the “1”) is pulse dialed, and subsequent digits are all pulse dialed.
E
Tells the CC-2401 whether or not to echo characters sent from the terminal.
H0 Hangup
Hang up and go into command mode.
H1 Off hook
Go off hook.
I
This command returns the chip revision code of the chipset. (A, B, C, etc).
I6
Displays the modem model number “2401”
:I
Reports the contents of the interrupt status register (S09). The WOR, PPD, NLD, RI, OCD and REV bits are
also cleared and the INT pin is deactivated.
M Speaker On/Off Options
These options are used to control the AOUT pin for use with a speaker.
O
This command returns the modem to online mode. It is used to return to data mode after an escape sequence
to resume communications with the remote modem.
RO Turn-Around
This command initiates a V.23 “direct turnaround” sequence and returns online.
