Subject: Problems with 50CT and 3COM 56k/Ethernet Card
Hi everyone,
Hotmail is messing up their already messed up system by installing some new
servers that pop up a lot more advertising, [time to Yahoo David ;-P], and
a new interface, and now all my mail is gone! Hopefully temporarily. So
I've re-subscribed to the Libretto list from my My-Deja account.
First of all, let me remind people that I'm working on a 50CT.
Last week I mentioned that I was ordering a 3COM Megahertz 56k/Ethernet
Combo card. Someone else (forgive my forgetting your name) was having
problems getting a Megahertz card running in their Libretto. I've been 3
days now, and have run up against a brick wall with 3COM support.
I got the 3COM Megahertz 3CCFEM556 56K/Ethernet PC card that I mentioned
seeing at the Centrex International website (www.centrex.com ... or
www.centrex-intl.com?). After installing the drivers, I was only connecting
at 24,000 bps, and tested transfer rates consistently at 2.3 - 2.4 K
Bytes/sec. while doing back to back tests with my old 33.6K modem that
consistently showed transfer speeds of 2.9K Bytes/sec..
In 3 rounds of calls to 3COM tech support, as per their advice, I:
1. Flashed the card to upgrade it to the V.90 specifications
2. Removed this card's drivers and installed the drivers for the
3CCFEM556B (with the added 'B' there) modem.
3. Tryed forcing the modem's connection speed with the following AT
commands:
AT&U20
ATZ
AT&F
AT&F2
None of the above resulted in getting a connection faster than 24000 bps.
The last call with 3COM ended at looking in Device Manager under "PCMCIA
Socket" where we looked at the properties for the "PCIC or compatible PCMCIA
controller". Under the "Resources" tab of those properties, the 3COM tech
person said that my settings were missing configurations for an interrupt
request, and a memory range. The only item listed under "Resources" was:
Input/Output Range 03E0-03E1
Also, under the properties for "Computer" where the interrupts are listed,
we noticed that there was nothing assigned to IRQ9. However the tech person
said that infrequently this setting may actually be there, but is hidden
The 3COM tech support person said I should ask Toshiba (so I'm here asking
you guys!) about "any advice on reassigning resources" for this 50CT, and
suggested the following:
_Finding out if a utility exists to reconfigure these resources.
_Also to check for a BIOS upgrade, although I'm pretty sure (not certain) I
have in fact upgraded that in the past.
_Also I should check to find out if these resources can be set manually in
BIOS.
_And last, I should check to see if there is a procedure for removing the
existing settings for this "PCIC or compatible PCMCIA controller" in Device
Manager, and then reinstalling them.
A couple of their support reps thought that this 75MHz CPU just might not
have the power to get this modem up to speed. The modem DOES in fact have a
hardware controller, I checked with them on that. And I imagine many of you
have managed to get 56K modems working in their 50CTs, right?
The other thing I'd like to do if I can find a friend with another notebook,
is to try setting up this card in a different system to see if the card
might be faulty.
Phew... well, thanks a lot folks. I'm crossing my fingers.
Matt
