Start up @value{GDBN} as usual, using the name of the local copy of your
program as the first argument.
+@cindex @code{target remote}
+@value{GDBN} can communicate with the target over a serial line, or
+over an @acronym{IP} network using @acronym{TCP} or @acronym{UDP}. In
+each case, @value{GDBN} uses the same protocol for debugging your
+program; only the medium carrying the debugging packets varies. The
+@code{target remote} command establishes a connection to the target.
+Its arguments indicate which medium to use:
+
+@table @code
+
+@item target remote @var{serial-device}
@cindex serial line, @code{target remote}
+Use @var{serial-device} to communicate with the target. For example,
+to use a serial line connected to the device named @file{/dev/ttyb}:
+
+@smallexample
+target remote /dev/ttyb

If you're using a serial line, you may want to give @value{GDBN} the
@w{@samp{--baud}} option, or use the @code{set remotebaud} command
(@pxref{Remote configuration, set remotebaud}) before the
@code{target} command.
