Quote from TOS14FIX.PRG docs follows: "1) A change was made to the BIOS call that sets the RS-232 port configuration. Specifically, it did not allow RTS/CTS flow control to be enabled. This is a problem for people with serial printers and high speed modems, since those devices use RTS/CTS flow control to start and stop data transmission so that the device can keep up with the computer. If you have Rainbow TOS, and you use a high-speed serial device which requires RTS/CTS flow control, you need this program in your auto folder." -- --- Stephen Goldstein steveg@cseic.saic.com My first Atari system?
