You can link modems. However most dial-up ISPs caught onto this and you
cannot logon with the same dial-up account twice - you have to have two
accounts and two phone lines.. Although some providers may actually offer a
"Multilink" package. With broadband available in many places and
inexpensive - it makes little sense unless it is the only choice you have.
You should also be aware that while you might get 112K downloads in some
cases, most will only be 66K downloads.. and definitely not faster than 66K
uploads.

See : http://support.microsoft.com/kb/307849/

To use multiple device dialing:
?Your ISP must support synchronization of multiple modems.
?You need to install multiple modems.
?You need a separate phone line for each modem.

Multilink is enabled automatically in Windows XP Home Edition and Windows XP
Professional.

Configuring Multiple-Device Dialing
--------------------------------------------
The Network Connections feature performs Point-to-Point (PPP) Multilink
dialing over multiple ISDN, X.25, or modem lines. This feature combines
multiple physical links into a logical bundle; the resulting aggregate link
increases your connection bandwidth. To dial multiple devices, both your
connection and your remote access server must have Multilink enabled.

Network Connections can dynamically control the use of lines that are using
Multilink. By allocating lines only as they are required, excess bandwidth
is eliminated. You can configure the conditions under which extra lines are
dialed, and underused lines are hung up, by changing Network Connections
settings.

Note that if you use Multilink to dial a server that requires callback, only
one of your Multilink devices is called back. This occurs because you can
store only one number in a user account. Therefore, only one device connects
and all other devices do not connect; your connection loses Multilink
functionality. You can avoid this problem:

?If the phonebook entry for the Multilink connection uses a standard modem
configuration, and the remote access server that your connection is calling
uses more than one line for the same number.
?If the phonebook entry for the Multilink connection is ISDN with two
channels that have the same phone number.

To configure a connection:
1. Click Start, click Control Panel, click Network and Internet Connections,
and then click Network Connections.
2. Click the connection that you want to configure (for example, a dial-up
connection), and then, under Network Tasks, click Change settings of this
connection.
3. Click the General tab, and then click each device that you want to use
for this connection.
4.Use one or more of the following steps:
?To configure dialing devices, phone numbers, the host address, country or
region codes, or dialing rules, click the General tab.
?To configure dialing and redialing options, or X.25 parameters, click the
Options tab.
?To configure identity authentication, data encryption, or terminal window
and scripting options, click the Security tab.
?To configure the remote access server and protocols that are used for
this connection, click the Networking tab. Also, click Settings and select
the Negotiate multi-link for single link connections check box.
?To enable or disable Internet Connection Sharing, Internet Connection
Firewall, and on-demand dialing, click the Advanced tab.

Notes:
?Depending on the type of connection that you are configuring, different
options and tabs appear in the connection's properties.
?For more information about a specific item on a tab, right-click the
item, and then click What's This?

Hope that helps clear things up...
