S10 Modem Problems

If you are using a Siemens S10 modem and are experiencing any of the following problems:

• The line is dropped no matter what @datec number you call
• Calls get dropped after a few minutes of connection
• Calls get dropped during login
• Modems cannot connect at all because the line condition is so bad

Often the Modem S10 register is set too low. Modem hangs up after carrier loss.

Procedures

Some modems are shipped to wait only 1.4seconds before dropping a call after a carrier loss.

Check that the S10 modem register is set to 6 seconds , this will allow the call to remain connected after carrier loss.

	Reset the modem, or PC if it is an internal modem
	If you're using Win 95 use the 'Hyper Terminal' to talk to the modem.
	To use the Hyper Terminal, click on Start , Programs, Accessories, Hyper Terminal - Icon Hyper Terminal
	At the prompt for the new connection type in MODEM then click Ok.
	In the Connect To box go to the box that has connect Using and select the Com port that your modem is configured on. Eg Com2 Don't use the modem description otherwise you have to type a telephone number.
	In the Port Settings window, click on Restore Defaults then click OK
	You should be looking at a blank Hyper Terminal Screen, you are ready to talk to the modem directly.
	To test if you are talking to the modem properly type in the letters 'at' then press enter, you should see a response on the next line down saying OK.
	Now we need to examine the S10 register. To do this type in 'at s10?' and press enter.
	A number will appear on the next line down, make a note of this number somewhere. It is the tenths of a second that the modem will wait before hanging up after carrier loss.
	This number should be set to 60. To do this type 'at s10=60' and press enter.
	Now we need to store this number in the modems profile so type in 'at &w' and press enter.
	Exit Hyper Terminal and try connecting to the Internet again.
