After you change the default value of the "Cancel the call if not connected within <XX> secs" check box on the Connection tab in the Modem tool in Control Panel, the Modemlog.txt file still shows the modem's S7 register set to 55 seconds. Regardless of the value you enter, the value is still set to 55 seconds.
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

Microsoft has confirmed that this is a problem in Windows NT 4.0 and Windows NT Server 4.0, Terminal Server Edition. This problem was first corrected in Windows NT 4.0 Service Pack 4.0 and Windows NT Server 4.0, Terminal Server Edition Service Pack 4.
The minimum value for this field is 55 seconds. Any number less than that results in the modem's S7 register being set to 55 seconds. To set the register to a value greater than 55 seconds, apply Windows NT 4.0 Service Pack 4 to the computer before changing the default value.
