I have Diamond SupraFax Modem 33.6 external.

this modem does work as a standard modem 28.8 but it would works alot better using its proper drivers.

I require NT4.0 drivers and 95/98 drivers would be even better, As I sometimes use this modem on all 3 OSs

Thanks

Not necessarily.
DSP (Digital Signal Processing) modems are meant to be used at the "factory" settings.

So, if you are using 'AT&F1' (3COM/USR modems) or 'AT&F' (all other modems), you will get "optimal" data-transmission rates.

Anyway, access:

http://WWW.DiamondLegacy.com/products/drivers/driver-index.htm 

and click on the link labelled:

INF Driver Files for Supra 288/336/56K Modems

and prove me wrong.  :-)

otta, I've used it as a standard modem, what makes me ask about the drivers is that NT RAS shows very low compression ratio's on download.

I'll download the drivers tonight

That depends on the "compressability" of your specific data -- the "factory-setting" for the modem should be enabling the compression-feature of the modem; since compression is being reported, it seems like the modem is doing (some) compression.

Actually the compression is the same with the new drivers (WinNT)
but I have another strange problem, NT reports more "CRC" errors since I changed the drivers. I think it may be due to the modem not reporting them as a standard modem? any comment

CRC == Cyclic Redundancy Check

When a packet is sent, some additional information (a "check-sum") is calculated, and is sent with the packet.

When a packet is received, the "check-sum" is recalculated, and is compared with the received "check-sum".
Any difference is a "CRC-error",
and indicates that the packet was corrupted in transmission, i.e., through the telephone-lines, or elsewhere.

Check that you've configured your modem for "hardware handshake", so that no information is "lost" between your modem and your COM port.

Other than getting your telephone-company to replace their wires from your home to their Central Office, you're stuck with the "quality" of those copper-wires.
