Win2K Modem problems

Modems will not connect above 28.8K in my Win2K system. I have 4 modems, Creative, SupraMax, US Robotics and HP USB external, and none of the 3 internal modems will connect above 28.8K. Pull them out and put them into the Win98 system next to it and they all connect at 37K to 44K consistently. Put them back into the Win2K machine and 28.8K max again. The external HP modem connects in the low 30k range on either machine. Used Hyper Terminal to set up (modem strings) and dial the modems manually but still only 28.8K.

Anyone have any suggestions?

System:
Abit KT7 Raid
Duron 700 (run at 700mhz to 1ghz)
2 Quantum 30GB ATA66 hard drives Raid mode 0
8X DVD
Plextor 8/4/32 CDRW
100MB IDE Zip drive
Radeon 32mb DDR
Soundblaster Gamer 5.1
NDC 10/100 network card
ADC USB 4 port controller card
Creative 56K modem
Supra Max 56K modem
US Robotics 56K modem
HP 56K USB modem
Windows 2000 Professional
128MB Crutial cas2 memory
 
Go to the manufacturers' websites and download the most recent win2k drivers... most of them time these are driver problems...
 
Downloaded the latest drivers from the manufacturers for Win2K and used them to build the system when the modem boards were first installed. System was originally built about 2 weeks ago.
 
what speed are your com ports set at?
Go to device manager, ports, and double click on the com port, then port settings, set it as high as it can go.
 
I have tried all of the port speed settings up to 460800. The USR modem only goes to 115200 though. Is it possible that the Abit KT7 motherboard is causing this problem, power regulation, interference, noise, ???

Considering the number of other problems I have had with this motherboard, and the Soundblaster, I would not be surprised at anything. The Soundblaster Live is definately a product that is not ready for market and if it were a car they would all have to be recalled.
 
Try turning the port speed down to 57600, not up. Then try the following init string:

AT&F&C1&D2&K3

Let me know what this does.

What you want to do is go into Network and dial up connections, right click on the connection and choose properties, and then click on configure under the modem. The port speed should be dropped to 57600 on the general tab, and you can stick the init string in on the advanced tab.
 
Finaly got to try the modem string and speed changes. Response said connect was 115.2kb. checked the modemlog.txt file and confirmed that it was still connecting at 28.8kb. Tried several downloads to confirm speed and they all ran about 2.7k byte/sec. transfer rate, confirming a 28.8 connect. The &F causes the modem to report the port speed instead of the actual conect speed. Adding an &W2 to the string caused it to report 28.8kb connect speed. I am totally out of ideas.
