Installation instructions for I-modem flash code rev. 2.0.9

IM020009.EXE is a ZIP archive containing the flash code for all 
internal domestic I-modem models.

The distribution files are self-extracting ZIP files.  Extract them into
and empty sub directory by executing the appropriate file while in that
empty sub directory.

There is a batch file called "GOINT.BAT" that will execute all the necessary
commands for the flash utility (PCSDL.EXE).  The actual flash code is 
contained within the .NAC and .SDL files.

GOINT.BAT needs to be executed the COM port as the only parameter from the
subdirectory you extracted the files to.  For example:

If your I-modem is on COM1: execute:

GOINT 1

If your I-modem is on COM2: execute:

GOINT 2

You will see it establish communication and begin the flash process.  The
process should take approximately 5 minutes.  Configured items such as 
SPIDs and DNs should be retained (ie. not overwritten).

IMPORTANT NOTE!

Many times new code will change the memory locations used by various 
registers.  BE SURE TO GO INTO A TERMINAL PROGRAM AND ENTER THE
FOLLOWING COMMAND!:

AT&F1S67=0S68=1S69=0&W

This will restore the factory default template, set S67 to 0, and
write these changes to NVRAM. It will also enable the enhanced auto
select and Turbo PPP features (S68). You may want to make a screen 
print of your current settings first  (ATI4).

USING NON-STANDARD IRQ ON YOUR COM PORT

The standard IRQ for a COM Port is as follows:

COM1: AND COM3:		IRQ4
COM2: AND COM4:		IRQ3

If you are using any other IRQ than the standards noted above, you must
manually inform PCSDL of the non-standard IRQ through the "-i" parameter.
For example, for rev 2.0.6 if the I-modem is on COM3, IRQ5 the PCSDL 
command line should be:

PCSDL -p3 -i5 -r57600 -vNA2.0.9 -vSD2.0.9 -nNAim -nSDiM -b
