# @Title: Python script sending all commands of a PRACTICE script to TRACE32
# @Description:
#  The program creates a connection to TRACE32 and sends all commands from the
#  specified PRACTICE file (*.cmm) to TRACE32 for execution.
#  It can also be called without a file name but it will wait for a command list
#  that should end with CTRL+Z
#
#  The port on which TRACE32 listens for API connections can optionally be
#  set with the --port <n> parameter.
#
#  Syntax:   t32remotedo.py [--node <ip-address>] [--port <number>] [file]
#
#  Example:  t32remotedo.py  --node localhost --port 20002 test1.cmm test2.cmm
#  Example:  t32remotedo.py  --node localhost --port 20002
#            go
#            break
#            step
#            ^Z
#
#  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.
