Release Note on Elite 2864(L) and Omni 288S, Version 1.13
============================================================
1. Fixed modem bugs:
--------------------

.Can not detect the CNI message in Russia with E2864L modem:
After answering the incoming call in Russia, modem will report
incorrect CNI message as "CALLER'S NUMBER: ?".
.Incorrect CNI report in Russia:
After answering the incoming call in Russia, modem will report CNI
message with an additional "0x00" null character before the actual
CNI number.
2) Special dialing feature:
.Cannot use off to on transition of DTR signal to initiate dialing:
When the "AT&D1&Z0=0,783942&M3" command is entered, the modem will
not dial when the DTR raises on condition.
.Failed to work with reverse dial function:
When the bit5 of status register S17 is set, the modem will not
change its role as an answer modem after completing the dialing
procedure.
.Incorrect repeat dialing with "A>" command:
When "A>" command is entered after modem resport "BUSY" in dialing
state, the modem will not repeat dialing with an redial interval
controlled by the content of status register S8.
.Cannot support up to 50 telephone numbers for dial backup:
When the "AT*B10" command is entered in E2864L model, the modem
will response "ERROR" instead of "OK".
.Store phone number incorrectly:
When the "AT&Z=138abc" command is entered, the modem will store an
incorrect phone number into the EEPROM.
3) RS232 interface procedure:
.Cannot answer incoming call automatically:
When the "AT&D0S0=1" command is entered and the RS232 cable is
disconnected, the modem will not automatically answer the incoming
call.
.Incorrect CTS delay with the content of status register S26:
If "AT&R0" command is entered in synchronous mode, the modem does
not control the CTS delay timing according to the content of S26.
.Fail to use the "CD on before the connect message is sent" feature
in *G1 security function:
If the bit3 of status register S38 is set, the modem does not turn
on the CD before sending the connect message in security function *G1
4) Error control with data compression:
.Cannot connect with MNP4/MNP5 in V.22bis mode:
When the "AT&N14&K1&T1" command is entered, the connect message
is "CONNECT 460800/V.22b 2400/None".
.Cannot connect with USR using MNP4/MNP5 error control mode:
When the "AT&K1" command is entered, the 2864 calling USR modems
will get an non-error control connection.
.Cannot connect with V42/V42b in V.22 mode:

When "A>" command is entered after entering "ATH" command in escape
state, modem will report "OK" response night times.
.Incorrect product information of OMNI:
If the "ATI0" command is entered, the OMNI modem will report "2864"
instead of "288".
.Incrrorect response of AT command:
When the "ATS0=300" command is entered, the modem will response "OK"
instead of "EROOR" and the content of S0 will be set as "255".
.Incorrect connect message:
When the DTE speed of terminal equals to 300 bps and the "ATZ4&T1"
command is entered, the modem will report connect message as
"CONNECT CONNECT/V.34 9600/V42b/SREJ".
.Incorrect help message:
When the "AT*?" command is entered, the modem will display some
garbage firstly and then the help menu.
.Display one more illeage line:
When the "AT+?" command is entered, the modem will show an additional
"Strike any key when ready" at the end of each page.
.Incorrect numeric response:
When user chooses the 9600bps DTE speed and sends "AT&FX4V0" command
to modem and forces it into the ALB operation mode. The modem will
report "12" instead of "12".
.Incorrect connect message:
When the "ATX6&N16&T1" command is entered, modem will report the
connect message as "CONNECT CONNECT" instead of "CONNECT" only.

PnP-ID as "ZX0100" instead of "ZX0400".
7) Security function:
.Cannot dial the telephone number with *G2 and *G4 security function:
When *G2 and *G4 function is used, modem will not call back the last
forty telephone numbers stored in modem.
.Insecure connection with secure function *G2:

procedure:
When you try to use D/V key to abort the handsaking procedure used
V.34 leased line mode operation, the modem may happen deadlock and
can not enter into data state successfully.
.Failed to retrain in V.34 synchronous mode:
When modem stays in V.34 synchronous mode operation, modem will
not retrain successfully when the line condition of channel is
aried.
.Improve the stability of V.27bis:

.22bis
connection, the modem will report "NO CARRIER" instead of "OK".
11) V25bis command set:
Cannot dial with the V.25bis synchronous operation mode:
When you plugs out the RS232 cable and then plugs in again, the
modem can not accept the V.25bis synchronous command anymore.
12) Lockup problem:
When the rate negotiation happens about one second after the
connection, the modem lockups forever with blinking both V34 and
V32b LEDs. And can not be abort with D/V key.
2. Fixed fax bugs:
------------------
1) Cannot answer the incoming fax with 2MB internal DRAM:
When the modem with built-in 2MB DRAM and entered with "+FCLASS=Z
+FZF=2 S0=2 &W0Z0" command, the modem will not answer the incoming
fax automatically if the DTE is turned off.
2) Cannot receive a fax correctly after a V.34 data connection:
If user switches between data and fax calling from the E2864 to
a Motorola or receiving a data call from a Motorola modem the modem
will hang up and it will no longer receive a complete fax call after
any data call.
