Readme - 5.49 Lucent Win Modem
Lucent 5.49 firmware for "LT Win Modem" has these
changes from prior (5.44) versions:
1. The handshake has been changed. The tick-tick-tick
sound of the digital impairment learning sequence is less pronounced. V.90
training now sends a scrambled sequence upstream to keep echo cancellers
disabled. This improves connect reliability to some servers with some call
routings.
2. Connect reliability problem calling Rockwell/Conexant-based servers over
circuits with long delay fixed. Initial fallback to V.34 had been failing in
some cases.
3. Improved V.90 performance on some lines.
4. Fixed a V.42 bis compression compatibility problem. In a rare case
downloading from certain servers, the compression dictionaries got out of sync.
5. Added V.250 commands toward Microsoft PC99 compliance. End users should not
be concerned about this, since no known applications currently use the new
commands.
6. Improved DTE queue handling in NT4 for some oddly behaved applications.
7. More setup actions can be controlled through setup.ini: copy or launch files.
8. Fixed setup/remove bug in NT4 that was removing devices other than the Lucent
modem.
9. Include ltmsg.exe that's in sync with modem driver, to avoid popping up
"invalid country" warning inappropriately.
10. Improved reliability of some PCI modems in some PCs when resuming from
suspend mode.
11. Improved reliability of wake-on-ring feature in some systems.
12. Fixed bug in NT4 multiprocessor machine.
13. Cosmetic change to display "NS 16550AN" for ISA PnP modem under
Diagnostics | More Info | UART.
*** TO INSTALL ***
Simply run this exe (modem549.exe). It should automatically run setup, which
will remove the current modem and all its associated files, detect the modem
again, and install it with the new inf file.
--------------------------------------------
*WARNING - While this software was designed for most Lucent LT-based Win Modems,
aka Apollo/Mars, there may be exceptions. You can always return to the firmware
you are currently using IF YOU ARCHIVE the current drivers. See: https://modemsite.com/56k/ltwin.asp#procedure
It is BEST to run the .exe and let the
Lucent SETUP program run to complete the installation; however, you may also be
able to update the firmware using the procedure on the above-referenced web
page. In some situations your modem may be renamed from a "LT Win
Modem" to a "Lucent Win Modem", and you may have to change the
dial-up-networking connection properties to specify the new modem name as the
modem to be used for the connection.
**TO FORCE THE [PCI] MODEM TO A SPECIFIC
COM PORT**: Edit the Ltmodem.inf file to uncomment (remove the semicolon - ; )
from the line: [ltmodem_CommVars_AddReg] HKR,, PORTNAME,,"COM2"
