# @Title: TRACE32 Remote API that use T32_Cmd() and T32_GetMessage()
# @Description:
#  TRACE32 Remote API sample program illustrating the use of T32_Cmd()
#  and T32_GetMessage() This demo send a command to TRACE32 PowerView
#  and request any AREA message.
#
#  Syntax:   t32apicmd.py  [--node <ip-address>]  [--port <num>]  <cmd>
#
#  Example:  t32apicmd.py --node localhost --port 20000 PRINT VERSION.BUILD()
#
#  TRACE32's configuration file "config.t32" has to contain these lines:
#    RCL=NETASSIST
#    PORT=20000
#  The port value may be changed but has to match with the port number
#  used with this python script.
