+NAME: lf_atten_mod_test.py
+
+PURPOSE:
+This program is used to modify the LANforge attenuator (through the LANforge manager/server processes) by using create() method.
+You can check the attenuator details and serial number by using show() method.
+
+EXAMPLE:
+Run with all serial number and module: python3 lf_atten_mod_test.py -hst 192.168.200.12 -port 8080 -atten_serno all --atten_idx all --atten_val 220
+Run with particular serial number(2222) and module(2): python3 lf_atten_mod_test.py -hst 192.168.200.12 -port 8080 -atten_serno 2222 --atten_idx 3 --atten_val 220
+
+"atten_serno" = serial number
+"atten_idx" = module name
+
+
+Use './lf_atten_mod_test.py --help' to see command line usage and options
