When not specified during the configuration stage,
the port @var{number} defaults to 3333.
+When @var{number} is not a numeric value, incrementing it to compute
+the next port number does not work. In this case, specify the proper

Note: when using "gdb_port pipe", increasing the default remote timeout in
gdb (with 'set remotetimeout') is recommended. An insufficient timeout may
cause initialization to fail with "Unknown remote qXfer reply: OK".
