navigate through the directory structure to pub/xdsl/hceth. From this site, you
can obtain document updates from the DOCS subdirectory and code updates
from the BINARIES subdirectory.
The code updates are stored in two forms in the BINARIES subdirectory. One form
is a self-extracting executable (with the extension .EXE) that contains the new
operational software along with the supplemental utilities required to load the
software into the unit via the serial port. The filename reflects the version of the
code (i.e., V010109.EXE would contain version 1.0.9).
The second form is simply the operational software itself. This can be used with
the Built-in Update procedure presented later in this chapter which directly loads
the software into the modem without storing the code on a PC. Files containing
the operational software only have the .NAC extension.
For serial port update, select the appropriate EXE file from the BINARIES directory
and store it to an empty subdirectory on your PC. You should execute the
self-extracting EXE to unzip the files to the local subdirectory. Continue to the
Installing Operational Software via DOS section.
3Com HomeConnect
ADSL Modem Ethernet
CD
If you have obtained an updated 3Com HomeConnect ADSL Modem CD, or if you
have erased the copy of the 3Com HomeConnect ADSL Modem Ethernet
Operational Software from your hard drive, you need to copy the operational
software from the CD to your hard drive.
1 Insert the 3Com HomeConnect ADSL Modem Ethernet Installation CD in your PC’s
CD drive (for example, drive d:). An installation menu will be displayed.
2 Click Install the HomeConnect ADSL Modem Ethernet.
3 Follow the prompts on your screen to finish the software installation. In addition
to installing the 3Com HomeConnect ADSL Modem Ethernet operational
software, this will also install the utilities and printable documentation.
The 3Com HomeConnect ADSL Modem Ethernet operational software (the *.nac
file) included on the CD is copied to your hard drive and not the 3Com
HomeConnect ADSL Modem Ethernet unit. It is installed to c:\Program
Files\3Com\3Com HomeConnect ADSL Modem Ethernet\Update.
Installing Operational
Software via DOS
Your 3Com HomeConnect ADSL Modem Ethernet Installation CD installs a
DOS-based utility program onto your hard drive. This utility program, PCSDL.EXE,
is invoked by a DOS-batch file, DL.BAT, which has also been installed to your drive.
In order to use PCSDL to load code to your 3Com HomeConnect ADSL Modem
Ethernet, use the console port straight-through console cable (provided) between
your workstation’s serial port and the unit’s console port.
To update the software from DOS, perform the following:
1 Using a terminal application such as HyperTerminal to test the serial connection,
set up the terminal application with the following settings:
9600 baud, No stop bits, 8-bit characters, no parity
2 Press Enter on your workstation. If the terminal application displays the '3com
homeconnect adsl modem ethernet>' prompt, the serial connection is
operational. You should now close the terminal application (Hyperterminal).
