-# @file Proptocols between SICS and High Voltage Controller 
-#
-# This is a driver for SICS to make following communication with the High Voltage Controller
-#
-#
-#  1. SICS uses TCP/IP protocol to interact with the HV component who shall provide an IP address 
-#     together with an port number.
-#
-#  2. Commands From SICS to HV component, 
-#       1. HV_START hv1=xxx, i1=xxx, hv2=xxx, i2=xxx
-#          :: Responses from HV component back to SICS are either
-#             OK (if the system start correctly), or
-#             Error Message (if the system does not start normally, the error message shall indicate 
-#             type of the errors)
-#
-#      2.  HV_STOP (This will stop/shutdown the HV component totally)
-#
-#      3.  HV_RESET (This will reset the HV component using the hv/i values specified in the Gumtree client GUI)
-#          :: Responses from HV component back to SICS are either
-#             OK (if the system start correctly), or
-#             Error Message (if the system does not start normally, the error message will indicate type of the errors)
-#
-#      4.  HV_STATUS (This command will send to HV component automatically and regularly, i.e. every 1 sec)
-#          :: Responses from HV component back to SICS is "hv1=xxx, i1=xxx, hv2=xxx, i2=xxx, system=rampingup;\n", 
-#             SICS uses this information to update their values in the SICS system and on the Gumtree client as well.
-#
-# 3. HV parameters to be dsiaplyed on the Gumtree GUI are, hv1, i1, hv2, i2, system 
-#

-#
-# The HV Controller can be installed with the following command,
-# ::scobj::hv::mkHV {
-#   name "hv"
-#   IP localhost
-#   PORT 55010 
-#   tuning 1
-#   interval 1
