MS-DOS uses the BIOS to write to the screen, and NNANSI writes directly to video memory, and can do scrolling by pointing the start of the video page down one row in memory. ObHack: Hmmm, let me see... I got an Acecat II 5x5" graphics tablet. I only have 2 serial ports, a mouse hooked to the first and a modem hooked to the second (a 16550A UART). I put a switchbox on the second port and though all was well. The tablet came with a neat program that lets it coexist with a mouse under MS-Windows 3.1. The only problem is that even if I switch the box to an unconnected setting, the tablet driver locks the serial port so I can't use the modem! I wrote a pair of batch files to start Windows that either add or remove the two lines that enable the driver using a DOS port of sed. I just have to exit and restart Windows to switch. I will probably pick up an extra serial port card soon, but in the meantime, it works! -- Chris Adams - cadams@HiWAAY.net Simulations Director & Counselor United States Space Camp/Academy - US Space & Rocket Center Abandon all hope, ye who PRESS ENTER here.
