As an design Engineer for Inrom Systems (I) Pvt Ltd.I had developed various communication packages for their products viz
Hand held barcode inventory controller system.
Time Recording Systems (TM01A & TM01E Respectively )
Digital Energy Meters etc etc etc.
During the course of my M_Tech Studies I had developed several small programs which Graphically animate & illustrate the various principles of digital communication The same may be downloaded here.
Again any one requiring help about serial communication may contact me at jahagirdar.vs@mailcity.com
