Does anyone know the standard frequencies used for tone dialing in
Australia? Want to write a little program that will autodial my
dumb modem by toggling RTS or other pin on the RS232 connector
and coupling this signal into the modem.
(Those interrested are welcome to mail me)

On another note does anyone have the VIDRAM utility so i can steal
RAM from the EGA addaptor to add to conventional memory?
