By "low-level," we mean commands that a human would typically not
invoke directly.
-Low-level commands are (should be) prefixed with "ocd_"; e.g.
+Some low-level commands need to be prefixed with "ocd_"; e.g.
@command{ocd_flash_banks}
is the low-level API upon which @command{flash banks} is implemented.
@item @b{ocd_flash_banks} <@var{driver}> <@var{base}> <@var{size}> <@var{chip_width}> <@var{bus_width}> <@var{target}> [@option{driver options} ...]
Return information about the flash banks

+@section Tcl RPC server
+@cindex RPC
+
+OpenOCD provides a simple RPC server that allows to run arbitrary Tcl
+commands and receive the results.
+
+To access it, your application needs to connect to a configured TCP port
+(see @command{tcl_port}). Then it can pass any string to the
+interpreter terminating it with @code{0x1a} and wait for the return
+value (it will be terminated with @code{0x1a} as well). This can be
+repeated as many times as desired without reopening the connection.
+
+Remember that most of the OpenOCD commands need to be prefixed with
+@code{ocd_} to get the results back. Sometimes you might also need the
+@command{capture} command.
+
+See @file{contrib/rpc_examples/} for specific client implementations.
