Hi,
I have a Zoom 56K PCI HCF Faxmodem, and I have found NO updates for the drivers. When I connect to the internet (TCP-IP) by dialing a local number and basically logging in, the modem shows up on the status as at 115200. As I mentioned before,its only 56K. Sometimes when I download things, they don't work due to 'internet hiccups'. At one time, I had a setup that was PERFECT and worked GREAT, but I lost that with a system crash. Even when I check my mail in Outlook Express, it disconnects as soon as I hit 'Send and Receive'. Any ideas of how I can make this work at Warp Speed would be helpful!!!

as for disconnecting after hitting send and receive, go into options in outlook express and uncheck "disconnect after sending and receiving". As for the poor performance of the modem, there are numerous strings you can try in you extra settings of your modem properties. ATZ or AT&F are a couple of common ones. One that really works well with most modems is S9=30. This string tends to stabilize the modem. You might also uncheck error control.

Disconnect AFTER sending and receiving doesn't work, it disconnects BEFORE. My Modems manual skips right over S9, and error control is a requirement for my ISP. Thanks anyways...

You should check that max speed is set to 57600 bps. Also check advanced port properties under modem properties and set all to "default".

Try looking at www.windrivers.com
modem support center. It gives various modem initialization strings which can increase reliability.
It also explains how to change your MTU and RCWIN values to tweak them for your modem.

If all else fails you can insert this S11=50
control Panel,click on modems,select properties,click on connections tab and select the Advanced button,in the extra settings box,enter the above.speeds up the dialing process

Try the following registry entry to speed connection:

1. Open the registry and find the key below.

2. Create a new string value named 'DefaultRcvWindow' and set it to '4288'. If 'DefaultRcvWindow' already exists, then simply modify the currentvalue.

3. Also create another string value named 'DefaultTTL' under the same key and set that to '128'. Again if it already exist, simply modify the value.

4. Exit the registry and reboot your PC.

1. Remove error control in your connection. (note that this has to be in your connection. Making this change in the modems control panel will not roll the change out to an existing DUN connection.)
2. Force MNP error control by typing ats48=128 in extra settings. (This is on the same screen for win9x anyways, so might as well do it while you're there.)
3. The false speed report from your modem is typical for a modem based on the Rockwell HCF chipset. Adding '&w2' to the end of the other string should report correct connect speeds, instead of port speeds.

Assuming that you have your outlook setup correctly, I'd put S10=100 into the modem string to give you a longer pause between disconnects. Also check your comm.drv in system.ini. comm.drv should = comm.drv. If it's someones elses comm driver it could be giving you connectivity problems.
