Motorolla modem disconnected

I have 56K, Internal Motorolla modem.
I install it in Win98 Second edition.
It works as a dial up server.
Some times when a user connected, his computer is disconnected from his side, but in my server it remaining connected, and no one could connect again. This connection appear for long hours, without any real connection. This problem occures one a day.

What can I do, please help.

Currently I dont have knowledge to solve ur problem.
But i dont think it is a problem with IRQ.
well, if there would have been a problem with IRQ, you will never be able to run it properly.

Any way,
Most of the internal modems are dumb modems. ie. they use your processor for many tasks.
However external modems have thier own chip, certainly not as powerful as your pentium or AMD chip. But they dont expect machine processor to do the work for them.

Check if you can set inactivity time out.
If there is no user connected, no data will come from modem and at last inactivity time out will occure. Thus server will hang up.

I set inactivity timeout to 4 minutes, but it seems that it has no any affect.

Actually, you said it stays "connected" with no real connection right?  Meaning that the modem is hung in the "on line" state even though it is not connected to the ISP.  I would replace the modem as the time out will not clear a hung modem. Sound to me like the modem is no longer able to reset after it loses the carrier detect signal.  How do you clear it now?  If the answer is restarting your computer, then I suspect I am right in my diagnosis since the only way to actually "RESET" an internal modem is to power it off briefly by restarting the computer.

I press disconnect in Dial Up server window, and it works fine after that, some one suggest to me to use External modem becuase it didn't use interrupt.

well.
My personally experience that external modem is better than internal modem.

Internal modems needs a IRQ to be assinged. WHere  as exteral works on com port. We already have a IRQ assigned to it.

did you mean IRQ is a problem during installation, or after that, for example if you install the Internal modem and you get an IRQ, did every thing will go fine

I swap my Interternal modem with External Adonics modem, my computer respond faster when I'm connected to the Internet or any one connect to my computer, befor it takes long time to open a site in IE and it hangs when I play MIDI.

I'll test the external modem for a week and watch the difference
