in ITU V.80 are recommended if available in the modem. If V.80 methods are
used, each response line shall be a separate extended in-band message.
Notes for Tables
The modem may insert a delay (e.g., 10 ms) between information text lines.
The code tables include values for data and fax calls. Some of the codes are
applicable only to data calls (e.g., data compression), some are applicable only to
call origination (e.g., busy, answering signal detection) and some are applicable
only to the answering modem (e.g., calling signal detection).
callCleared codes from 3.6.4/V.58-1994
callCleared: indicates that the DCE has gone on hook and that the previously
existing network connection has been cleared. These value are hex, converted
from decimal in V.58. callCleared codes are described in Table 3-11.
