CHAPTER 6: Power Up and Configuration Menu Options
6.2 Power Up Message
The A/S-4 sends out the message in Figure 1 on power up or the raising of DTR (DATA TERMINAL READY) on the terminal device. This message informs the operator that the A/S-4 is ready to try to match the operator’s terminal or terminal emulation package with the VDU (VISUAL DISPLAY UNIT) list in the memory. The operator may now type the “HOME” key on his/her terminal so that the A/S-4 may match the VDU device with the internal VDU list so that the clear screen, home cursor, position cursor commands, etc. to the VDU will be correct. If no match occurs, the A/S-4 defaults to the IBM 3101 VDU command set. This is not a problem if your VDU is not an IBM 3101, as you may change the VDU by the use of menus. If your terminal does not have a home key, you may hit the space bar and set up the VDU by the menus. Hitting the space bar leaves the internal VDU the same as the last VDU used with the A/S-4. After typing “space” or “HOME” the A/S-4 will output the A/S-4’s main menu. If a VDU match did occur, the screen will clear before the main menu is displayed, otherwise the VDU device will scroll.
