■ This document addresses the following upgrades;
1. Modem firmware by Microcom FirmUp(tm) Windows Applet
2. Modem firmware update with Terminal Emulation Software
■ FirmUp(tm) now features enhanced Windows95(tm) compatibility for both
PCMCIA and Parallel Modems. FirmUp will automatically switch to
serial mode until the firmware upload process is complete. No
additional configuration is necessary for notebook computers under
Windows95(tm).
■ The following Microcom Modems are Flash ROM Upgradeable:
DeskPorte Fast Plus TravelPorte Fast
DeskPorte Fast TravelCard 28.8 P
Deskporte Fast EP Travelcard Fast
DeskPorte Fast 28.8 P HDFast
┌─────────────────────────────────────────────────────────────────┐
│ NOTE: │
│ External Parallel Modems must be upgraded by Serial Connection. │
│ Firmware can NOT be upgraded through the Parallel port. │
└─────────────────────────────────────────────────────────────────┘
■ Firmware files for all Microcom FlashROM Upgradeble Modems are
available at the following locations:

Basic Installation Procedure for the Microcom FirmUp(tm) Applet
---------------------------------------------------------------
1. Obtain the current firmware file for your product.
2. Create a directory for the FirmUp program files on your hard drive.
Example: MD c:\firmup) Copy all of the included files to this
directory.
3. Install For Windows 3.xx:
Create a program item by selecting File/New
Description: Firmup
Command line: C:\Firmup\Firmup.exe
Working Directory: C:\Firmup
Click on Change Icon.
Double click the icon
Click OK
Install for Windows 95:
Open Explorer and change to the c:\firmup directory. Create a
shortcut for firmup.exe and drag to the location of your choice.
4. Update Procedure
Execute FirmUp by double clicking on the icon. Select the correct
com port and modem type. Click on the [INFO] button. If you
receive a "Modem not Found" error message, recheck your COM port
selection.
Now select the correct radio button for your Microcom modem
product.
Click on the [Update] Button. A file selection dialog box will
appear.
Select the correct path to the firmware file.
Example: c:\firmup\M0853318.DPF
Now click on the [OK] button and the update process will begin.
What to do if the Firmware Update Fails:
----------------------------------------
- Windows 3.11 Flow Control Mismatch:
Microcom Modems are configured to use hardware (RTS/CTS) flow
control by default. Windows 3.1x default settings are XON/XOFF
flow control. You can optimize your port settings by going into
Main -> Comtrol Panel -> Ports -> COMn . Change the Flow Control
setting from XON/XOFF to "Hardware" on the drop down selection
box.
- Use a Slower Port Speed:
For Windows 3.11: Select a Port Speed of 9600 bps or lower in
Main -> Control Panel -> Ports -> COMn
For Windows 95: From the START Menu, select Settings ->
Control Panel -> Modems Icon -> Modem Properties Tabbed Page ->
Advanced Settings. Change Serial Port Speed to 9600 bps
- Regarding 16550 UART Serial Support:
The TravelCard Fast and TravelCard 28.8 P have integral 16550
support.
The firmware update procedure for all serial-connected Microcom
modems is greatly facilitated if the serial port is supported by
a 16550 equivalent buffered UART chip.
The actual main code file for Microcom FlashROM upgradeable
products is an ASCII Hex Dump file. Each line of the firmware
code is protected by a checksum. In the event that a bit is
"dropped", the checksum will fail. The 16 byte buffers in a
16550 or equivalent serial port will greatly reduce the
possibility of a checksum failure due to dropped bits.
- Shut Down all other Processes while Updating your Firmware:
FirmUP will have a greater possibilty of success when it does not
have to compete with other applications and processes for
interrupt service. We recommend that nothing else should be
running for the duration of the update process.
- Reset Factory Defaults for Deskport Fast - All Models:
Experience has shown that the update process may be eased by
resuming a factory default configuration for the DeskPorte Fast,
DeskPorte Fast+ and the corresponding rack mount models. This can
be quickly accomplished by switch setting. Open SW2-4 and turn
the modem off and on. Leave the switch open. Proceed with the
update procedure. Restore the switch to the closed position and
reconfigure the modem.
How to Flash Update Modem Firmware with Terminal Emulation Software:
--------------------------------------------------------------------
The following terminal emulation packageshave been tested and found
to be capable of supporting this procedure.
CrossTalk for Windows and DOS TE/2 for OS/2
Procomm Plus for Windows and DOS HyperAccess for OS/2
MicroPhone Pro for Windows ZOC for OS/2
QuickLink II for Windows and DOS LiveWire for OS/2
Carbon Copy 6.1 terminal mode
Qmodem Pro for Windows and DOS
Telix for Windows and DOS
{COMMO} for DOS
Term90 - Norton Commander 4.0
HyperTerminal - Windows95
- Basic Steps for Terminal Emulation Software:
Set Serial Port Speed in Software to 9600 bps
Set Flow Control in Software to Hardware Flow Control (RTS/CTS)
If your Software supports only Software Flow Control, send AT\Q1
command to modem (XON/XOFF Flow Control)
Set ASCII Transfer Options in Software:
Character Pacing = 0
Delay between Linefeeds = 0
Send AT^H <enter> to modem to begin Update Process
Immediately begin an ASCII Upload of proper main code firmware file
to your Microcom modem.
There will be no screen output during the actual update process.
A successful upload will echo the message "MODEM FIRMWARE UPDATE
COMPLETE" to your terminal screen.
If you receive any error messages, refer to the "What to do if the
Firmware Update Fails" section above.
The upload process should take three to seven minutes to complete.
