I have a Diamond SupraExpress 56e Pro Modem.
This Modem is being used on a Pentium 4 P.C. running the
The Modem is being used to support a 24/7 connection to my ISP.
When my ISP periodicly re-cycles the Line and drops the connection, all of the Lights go off except, naturally the PWR (Power) light and the TR (DTR) Light.
When this occurs, I have to physically turn OFF and ON the Modem in order to get PPP to reconize the dis-connect.
This is not the way my other Modems worked.
I have attempted to place in the setup various AT commands
I would appreciate very much if someone could tell me the option that I have to enter to get the DTR signal to drop when the connection is broken.
Thanking everyone in advance for any information on solving this problem.

DTR = Data Terminal Ready.
In this instance, the computer/computer COM port is the data terminal. The modem is the data set. The computer controls the DTR signal. The computer/COM port stays in a ready state, so the DTR signal correctly stays high.
Would seem to me that the PPP program shouldn't use the DTR signal to detect loss of conection; but, if that's your only option, you'd need to use a breakout box or build a custom cable to force DTR low by, for example, to CD.

Thank you for responding to my problem so fast.
The line and the Software controlling it, PPP, are working
This Modem is not working like the other ones did.
I believe its some type of command to force this modem
Thank you for your attempt to help anyway.
