This is the file I've been sending to delphi users.
The Zoom Fix Nov. 8, 1995
I STRONGLY RECOMMEND YOU PRINT THIS FILE FOR REFERENCE !
advised I am not a zoom rep, have no connection to zoom
in any way
and I am only doing this to show you how I got my zoom model
110 RPI+ to
work properly. I can not guarantee it will work for your
system & setup.
These basic instructions should work to make the Zoom model
110 14.4 RPI+
modem able to upload file attachments and download in Delphi
at high speed
and without lockups.
Zoom Model 110 fax/pc-modem 14.4 with RPI+
Comit for Windows
Delphis new GUI
Zoomt's RPIKIT4.EXE (free download from Zoom see below)
486 or better compatible systems
(might work for 386 too, it does in AOL)
To test for your modem type and chipset go to windows program
manager and double click on your TERMINAL icon (mine happens
to be in my accessories group) When the screen comes up
the following command:
ati3 (that's an i not an l) now hit return or enter
Your modem chipset and type will be reported, write this
for future reference. If you have RPI+ and a chipset of
1.625 or higher,
following these instructions will probably help you, if
you have a lower
chipset or have RPI only they probably won't help you.
You may be able to
obtain a chipset upgrade from Zoom.
To test your Com port, exit windows completely (don't use
prompt) At the C: prompt type the following command:
msd now hit enter or return
Your Com port uart chipsets will be displayed. It is best
to install your
modem on the Com port with the highest uart speed. 16550
is desireable but
even if you only have 8250 the following instructions will
don't stop now! Go to Comit...
Assuming you have RPI+ Comit modem selection is:
3 modems using RPI+ firmware (string line must be blank)
Delete any string lines in the block if they are there!
Don't worry, your modem will use the default!
Comit Port settings are:
1, none, 8 (for 8250 uart you may have to use 1,none,
lock baud rate
hardware flow control
DO NOT ENABLE V42 SOFT!
You must have your modem operational even at low speeds to
You must have installed Delphi, Windows 3x, Comit for Windows,
You must download RPIKIT4.EXE from Zoomt and place it in
directory on your hard-drive. I have RPIKIT4.EXE and am willing
to upload it
if you need it. The suggested directory to create for SETRPI
and assuming =
your hard drive is C is; C:\SETRPI
You can find RPIKIT4.EXE and other files on the Zoom web
Create a directory called SETRPI and dowload or copy RPIKIT4.EXE
Once RPIKIT4.EXE is downloaded into this directory, in windows
manager, double click on RPIKIT4.EXE, then double click on
this will set up the Winrpi software and create a new program
complete with new icons. Go to your program manager, make
new group is open and double click on the msdos icon. This
correctly copy the new modem data file to your Comitw directory.
Go to the program manager and the new group of icons again
double click on the setrpi icon. A screen will come up, test
your com ports for modem location and chipset. If you do
RPI+ these instructions may not work for your modem. I've
fixed an RPI+ and therefore am not sure. Once revealed, write
the modem type and chipset etc. for future reference. Now
same screen click on driver and install the wrpi.drv You
a message that says it couldn't rename windapi.dll to windapi.dbk.,
restart windows anyway. Now go to your file manager, copy
(windows\system) windapi.dll file to any other directory,
as windapi.dbk then move this renamed file to your windows\system
directory. Now you've got both versions in case you want
back to windapi.dll for some reason. Exit windows and re-boot.
Go to RAW DOS. (not windows dos)
If you have dosshell loaded, fire it up and look at your
windows directory system.ini file. If you don't have dosshell
change to your windows directory, type the following command;
type system.ini | more
look at the [boot] section of this file... my last 4 lines say exactly this:
Carefull... I don't have multimedia so you may have more drivers!
If your "key" lines are different, then best thing to do is to
print a copy of your existing file and save it for future
reference, just in case you have to fix something later.
I consider lines 1,3, &4 of the above lines to be "key" lines
While in DOS fire up your editor and manually edit the
3 key lines of your windows\system.ini file to be exactly
like the "key" lines above. I would suggest EXACTLY in every way.
Don't miss the ; in line 3 above. Now re-boot your computer.
Now log in to Delphi and click on tool box
click on dial setup
click on modem setup
make sure you've set your modem port (my happens to be Com2)
set your speed at 19200
select modem type from the list (I selected Zoom Faxmodem VFX 14.4 - v32.bis)
my IRQ is set at default
my IO address is set at system
Now click on your red and white mail icon, usually at the upper
right of your screen
click on special
click on settings
check them: The only fields with anything other than * in them should be:
Baud rate 19200
Com port(as I said mine is 2)
Flow control should be hardware: That's a lie but don't tell the system!
Parity none (it works for me)
X at CLRF
X at show trace window
as I said before, except for an * in the modem and ID screens
everything else should be BLANK.!
Now... exit, reboot and log in again
I hope everything is working OK now!!! Try it and see!!!
If it works you've done great... BUT there's more!!!!
Now that that's out of the way you may have an opportunity
to increase your speed! Check your notes on the Uart of the
modems Com port.
If you have 16550 uart you can reset all baud rates to 57600
If you have 16450 uart you can reset all baud rates to 38400
If you have 8250 uart you must leave all baud rates at 19200
Note: If you've reset your baud rates to 57600 and transfers
seem to slow down then lower the setting to 38400 or if necessary,
back to 19200.
For those of you that have RPI instead of RPI+ you may have
to try a different or Custom modem setting in Comit, I can't
You'll have to experiment or talk to Zoomt (tech) if you
They'll probably try and sell you an upgrade, I personally
experiment and work with what I've got.
If anyone has problems just let me know via email, I'll try to help.
