o (0x6F)

Buffer Overrun.

c (0x63)

T.30 fax calling tone (1100Hz). The time interval between
reports is 4.0 seconds.

e (0x65)

Data modem calling tone (1300Hz). The time interval between
report is 4.0 seconds.

h (0x68)

Line current break (local phone goes on-hook).

H (0x48)

Line current  detected (local phone goes off-hook).

s (0x73)

Silence  detected. The DCE has determined that there was no

voice energy present at the beginning of the voice receiving
session followed by a period of silence greater than the amount of
time selected by the +VSD command.

q (0x71)

Quiet  detected. The DCE has determined that there was voice

energy present at the beginning of the voice receiving session
followed by a period of silence greater than the amount of time
selected by the +VSD command.

$ (0x24)

Bong Tone (300Hz for 1 second).

l (0x6C)

Loop current interruption. This may be a remote hang-up.

b (0x62)

BUSY. If the DCE continues to detect  BUSY , it may report

this event repeatedly. The delay between reports is 4.0 seconds.

u (0x75)

Transmission Buffer Underrun. The DCE will report this code if
the DCE's buffer becomes empty without first receiving a
<DLE><ETX> or a <DLE><CAN> command.

a (0x61)

Data answer tone. The delay between reports is 4.0 seconds.

Action Commands in Voice Data State

The DTE may initiate actions by inserting a <DLE> shielded code into the data to
the DCE. The form of the action is <DLE><code>,  where <code> is one of the
character values listed in the following table:

<code>

Event Report Description

<NUL> (0x0)

Does nothing. The DTE can use the code to refresh the

DTE/DCE Inactivity Timer, instead of XON.

<DLE> (0x10)

Two contiguous <DLE><DLE> codes indicate a single <DLE> is
in the data stream.

<SUB> (0x1A)

<DLE><DLE>  in the data stream.
