Description
Return On-line to Data Mode.
0: If the modem is in the on-line command state, the O0 command causes it to go to the
on-line state of the previously established connection. If the modem is off hook in the
idle (off-line command) state, then the O0 command causes it to go to the handshaking
state. Originate or answer mode is determined from the last D or A command, or R dial
modifier that was selected. If the modem is on hook in the idle state, or if the modem is
a test state, then the "ERROR" result code is returned, and no action is taken.
1: If the modem is in the on-line command state, the O1 command causes it to go to the
on-line state of the previously established connection, and retrain its adaptive equalizer
(if applicable). If the modem is off hook in the idle (off-line command) state, then the O1
command causes it to go to the handshaking state. Originate or answer mode is
determined from the last D or A command, or R dial modifier that was selected. If the
modem is on hook in the idle state, or if the modem is a test state, then the "ERROR"
result code is returned, and no action is taken
3: If the modem is in the on-line command state, the O3 command causes it to go to the
on-line state of the previously established connection, and issue a rate re negotiation
sequence (if applicable). If the modem is off hook in the idle (off-line command) state,
then the O3 command causes it to go to the handshaking state. Originate or answer
mode is determined from the last D or A command, or R dial modifier that was selected.
If the modem is on hook in the idle state, or if the modem is a test state, then the
"ERROR" result code is returned, and no action is taken
Also note that as the O command returns the modem to the online state, the protocol,
compression, and connect message (as enabled by the W command and S95) will be
displayed as if the connection was just being made.
Select Pulse Dialing. P will apply to all subsequent D commands, until altered by the T
command or the T dial modifier. Note that P is both a command and a dial modifier.
Result Code Control. Result codes are informational messages sent from the modem and
displayed on your monitor. Basic result codes are OK, CONNECT, RING, NO CARRIER, and
ERROR. The ATQ command allows the user to turn result codes on or off.
0: Enables modem ot send result codes to the computer (default).
1: Disables modem from sending result codes to the computer.
Select S-register r. Sr is the command to query or write to the selected register.
Sr=n:
Select S-register r, and write value n to S-register r. Limited to writeable S-registers.
Sr?: Select S-register r, read and report its value.
Select Tone Dialing. T is both a command and a dial modifier. Applies to all subsequent D
commands, until modified by the P command or the P dial modifier. This command
instructs the modem to send DTMF tones while dialing. This is the default setting.
DCE Response Format. Vn controls whether result codes (including call progress and
negotiation progress messages) are displayed as words or their numeric equivalents.
0: Displays result codes as digits.
1: Displays result codes as text (default).
Result Code Option.
0: CONNECT result code reports DTE speed. Disable protocol result code.
