| MC Tl Posts: 1 | Posted - 11/14/2000 7:30:56 PM    I built a system using a Tyan S2390 motherboard and I am running Windows NT 4.0 with SP5. I am using a USR 5687 (56K) internal ISA modem. I keep getting disconnected from my ISP after about 1 minute of inactivity. I have connected my old PC and it doesn't disconnect after a period of inactivity. It appears that the APM function in the BIOS is disconnecting the COM ports after a period of inactivity. Tyan technical support tells me I need to check my modem settings to see if it is set to disconnect after a certain period of inactivity. That is not the problem. They can not tell me how to disable the APM/ACPI functions in the BIOS or how to get around this problem. I have seen posting on Deja.com from people running Linux and stating that they had to use external modems or use PCI modems. I connected an external USR 83901 (28.8K) modem and experience the same problem. I have also tried to disable APM, ACPI and set the modem IRQ in the Advanced Power Management section of the BIOS without any luck. Any help would be greatly appreciated. Thanks. |

I would suggest - leave modem speaker on and examine modem diagnostic ati6 after disconnect for reason; also see what modem log shows. Try to log in to your ISP using Hyperterminal and see how long it will stay connected when idle (you can't do anything after login to ISP w/ Hyperterminal anyway). Try another ISP test connection if possible.
