Upgrading the Courier V.32 to 56k
Upgrading HST modems
Courier Dual Standard Fax with
v.32bis and ASL
This modem will do an honest 21.1K as is.
U1 TI PD17278PJ (?)
NOTE: If your daughtercard has a 32MHz oscillator, that is non-flash capable. The base card may take the upgrade daughtercard, which has either a 40.32 or 50MHz oscillator.
The following information was extracted from the 3Com site HERE
Courier Modems that Require a Daughterboard
How do I
find my model number?
This includes the following model numbers:
Finding an X2 Daughtercard
(b) daughtercard = hardware upgrade for the "small" size from 16MHz v.32 (128K EPROM, 32K RAM) to 20.16 MHz (256K EPROM, 32K RAM) and Terbo + V.FC options
(c) BIOS flash = firmware upgrade via software using flash loader, applies to daughter-card-upgraded as in (b) above or for the models listed in my previous post, taking them to options HST, V.32bis, Terbo, V.FC, and V.34+. This _software_-executed upgrade also increases the EPROM to 512K and the RAM to 64K. The unit then also has X2 capabilities as well, but one needs to pay USR $60 for a key code to exercise after dialing in to their X2 upgrade bulletin board, which then activates the X2 capability. A further firmware flash upgrade to V.90 from X2 is free.
There is, of course, a similar upgrade path for many of the Sportster 28.8/33.6 internal and external modems to X2 and V.90, which also cost $60. But they won't have all the communication protocol options that the Courier has when it has been transformed.
That is, the V.EVERYTHING means exactly that -- the unit will communicate using any USR-certified protocol.
Possible "Good" Modem ID
I have no _internal_ MCA modems, but suspect that any US/Canada Courier-IDed internal PS/2 modem would be upgradable to V.90 if it has, or has been upgraded to, the options V.32bis, Terbo, VFC, V.34, and has a 20.16MHz or 25 MHz clock frequency. This information is ascertained by asserting the ATI7 command to the modem using a terminal emulator.
A list of the modems that I have which I know are software-upgradable, as follows (legend on the front bezel):
_______Model Name________________________|_Model Number__
V.EVERYTHING with V.34 - - - - - - - -- - - 00122400
The single common factor between these is that they all have a barrel
plug connector for the power
The 56KBPS Technology Courier V.EVERYTHING also uses this power adapter spec (have one here). It already had V.90. That is the ATI7 Options string was:
No Courier modem with a 4-pin keyed round connector is directly upgradable,
because these models only have 16 MHz or less clock frequency. To be upgraded
(if it is still possible) they require a daughter-card replacement -- about
$35 IIRC. I haven't seen one of these that operates above 14.4 (19.6?)
Kbps natively. The 4-pin keyed connector is similar in size and appearance
to a mini-DIN PS/2 mouse/keyboard connector, but with a different pin arrangement.
I suppose an internal modem connected directly to the bus _might_ give
quantitatively faster file and
Is there a PCMCIA adapter for the PS/2 16-bit MCA slot? If so, that
might be a profitable
The $99 for the daughterboard upgrade does not include the cost of the 56kbps/x2 enable key.
Obtaining a 56kbps/x2 Enable Key
(Editor's Note: I have a Courier v.32bis w/ASL in my 9595OYT- have yet to get the $60 V.90 "key", so I'm making do with 28K+...)
an HST modem
YES! I tried the original daughtercard from my Courier V.32bis and it worked! It runs at the 21.1K rate the courier did before the upgrade daughtercard.
Important info- if the number on
the front end of the main modem board is 0185, then the 3com Product #
80-000953-00, Courier V.34 DS FX DB UPG should work.
What does this mean?
If you have the Microchannel Addiction Disorder, this is a way to get
that v.90 MCA modem and show off to your friends. But it will cost $160
for the upgrade card plus the "key". You decide.

Wake on ring feature seems to be a rework. There is an IC that looks
to have been snapped in half and glued upside down onto U18. Two wires
run from the added IC segment, one to R54, the other to the left pin of
the header P2.
