RE: 56K Modems - Do I really want mine?

I'm using a PM3 with ComOS 3.7 and the old modem cards. I have an IBM 760e
with a MWave modem. When I boot the laptop in NT 4.0, I MUST use *TH8 in
my init string to connect. (Or I get random gibberish on the screen instead
of a Login prompt.) According to the MWave help page, this increases the
Signal to Noise Ratio required for a given speed.

When I boot the same machine in Windows 95, I don't need the init string.
Go Figure.

The Mwave version I loaded is 2.2 (first available from IBM in May97). So
far, I haven't found a way to identify the version of MWave running on a
machine, I had to reload it just to make sure it was 2.2.

Is there any word about the seemingly broken V.42 implementations that hang
up after 12 resyncs? Is this a Livingston problem or a problem with all
(or most) modems? Is there a fix? Should I try and get MNP to work? Is
error control and modem compression really not necessary since I'm using
PPP and PPP compression (what ever that is) anyway? What do people think?

Finally, on a completely different subject: I have people calling in from
places like Brazil and the UK on very poor quality lines. With our old
analog modems held together with duct tape on a shelf, we added the init
string S10=50 so that the modems would not hang up until 5 seconds after
Carrier Detect drops. This seems to help. Is there anyway to do something
similar with my Digital Modems? We are new to this PM3, and I want to have
all my i's crossed and t's dotted before we switch users over to it.

Thanks in advance,

P.S. I really like this list, I've learned so much about modems and stuff
that I'm nearly ready to quit and start a new life making pottery!

I'm sure Livingston tested the MWave with the latest drivers, but that
doesn't change the fact that I have yet to see an MWave the worked
properly. I'm sure the MWave *works*, but not all that well.
Here's a web page where you can find all kinds of neat INIT strings that
fix various modems that are "broken":

I'm not sure if the USR Sportster fix is listed in there, but we've had
success with "ATS15.7=1".

It wasn't that *Hilarious* at the time he wrote the letter... About the
only reports that were coming in at the time, were not good at all.

I hear there is one, but what is it? When will Livingston ever post some
of these workarounds or even acknowledge them?

Check out this URL
http://www.livingston.com/Marketing/Products/56Krules.shtml
and read the list of client modems that are compatible with the PortMaster
3? Look what number 27 is?
