7. Qgrifo bus SOFTWARE DESCRIPTION As already stated QTP 12 is a complete video terminal It shows on the display any characters received from communication line except the commands that are recognized and executed and it transmits back on the same line the possible results of the executed commands and the codes of keys pressed In other words it acts a slave dumb terminal controlled by an external command unit that can be placed even at a long distance These operations are automatically performed by the on board firmware that is programmed and executed from QTP 12 CPU The on board firmware manages also a local setup which allows the user to define some working conditions by using the display and the keyboard of QTP 12 This chapter describes the main features of QTP 12 software functionalities while the following one reports a detailed description of the recognized comand sequences that can be used to benefit of all the potentialities of the terminal In corrispondence of the first order on the received grifo CD are supplied many complete and useful demo programs either in executable and source format these can be used as received with no modifications for a first test of the product and then changed or partially used to develop the user application program LOCAL SETUP Thanks to a proper local setup mode the user can select some parameters of communication protocol define some working condition
