- stdio : READ, WRITE
This will permit the separation of semihosting message from OpenOCD log,
and separate semihosting messages per core.
syntax: arm semihosting_redirect (disable | tcp <port> [debug|stdio|all])
this allows to select which operations to be performed via TCP (debug,
stdio or all (default)).
Note: for stdio operations, only I/O from/to ':tt' file descriptors are
redirected.

- The target can make a semihosting call with <opnum>, passing optional
