+              Sometimes, on a noisy phone line or even on a line with
+              call waiting enabled, your modem may hang up because it
+              thinks (incorrectly) that it lost carrier.
+
+            <p>
+              There's a setting on most modems for determining how tolerant
+              it should be to temporary losses of carrier.  On a USR
+              Sportster for example, this is measured by the S10 register in
+              tenths of a second.  To make your modem more forgiving, you could
+              add the following send-expect sequence to your dial string:
+<verb>
+  set dial "...... ATS10=10 OK ......"
+</verb>
+
+            <p>
+              Refer to your modems manual for details.
