/* *********************************************************************************************
* @Title: Sample program to execute TRACE32 commands from a system shell.
* @Description:
* This application creates a connection to a TRACE32 PowerView instance and sends a
* TRACE32 command to that PowerView instance for execution.
*
* By default the port on which TRACE32 PowerView listens for API connections is 20000.
* Optionally the port can be send with the port=<n> parameter.
* The port number must match with the definition in config.t32 of the PowerView instance you
* want to receive the command
*.
* The optional parameter wait=<ms> will cause t32rem to wait (after sending its command) until
* no more PRACTICE scripts are running in TRACE32 - or the given timeout elapses. Without the
* parameter wait=<ms>, t32rem will not wait until all PRACTICE scripts stop running.
*
* A binary of this sample can be found in <t32>/bin/<os>/t32rem[.exe]
*
* Syntax: t32rem <hostname or ip-address> [port=<number>] [protocol=NETASSIST|NETTCP]
* [timeout=<s>] [wait=<ms>] <command>
*
* Example1: Set a breakpoint on main():
* t32rem localhost port=20000 Break.Set main
*
* Example2: Open the Break.List window:
* t32rem localhost port=20000 Break.List
*
* Example3: Start a PRACTICE script and waits up to 5000.ms until it stops:
* t32rem localhost port=20000 wait=5000 DO ~~/demo/practice/pcmd.cmm
*
* Return values:
* 0 OK
* 1 Error accessing TRACE32.
* 2 Failed to connect to TRACE32. (No TRACE32 with an open API port at that socket)
* 3 Invalid input. (Invalid ip-address/hostname/port or too long command)
* 4 Timeout while waiting for PRACTICE scripts to stop running.
