Description of the Modem Responses Key in the Windows Me/98/95 Registry

This article describes the following modem Responses key in the Windows Millennium Edition (Me), Windows 98, or Windows 95 registry:

The Responses key contains strings that the modem might report to Windows Me/98/95 in response to a command or during the connection process. The name of each subkey is the text of a single modem response, and its data is a 10-byte binary value specifying the meaning of the response to Windows in a coded format. The first two characters (byte 0) specify the meaning of the response code, using one of the following values:


NOTE: The 1C and ID values are not included in Windows 95.


The second two characters (byte 1) specify information about a connection that is being made. It is used only for response codes of Negotiation Progress or Connect types, and is one of the following values:



The next eight characters (bytes 2-5) specify the modem-to-modem line speed negotiated in bits per second (bps). The characters represent a 32-bit integer, doubleword format (byte and word reversed). Common examples for this value include the following:



The last eight characters (bytes 6-9) indicate that the modem is changing to a different port or Data Terminal Equipment (DTE) speed. Usually, this field is not used, because modems make connections at a "locked" port speed, regardless of the modem-to-modem or Data Communications Equipment (DCE) speed. However, for modems that support only "direct" modes, you can lower the DTE speed by specifying a negotiated DTE speed for a response code, using the same format as the DCE speed described in the preceding table.
