From: Lawrence Finkel <FINKEL@COLUMBIA-20.ARPA> I have a Mac and a Novation JCAT 300 baud Auto-dial modem. However, in order for the modem to dial, a signal must be sent to the modem's OHK (off-hook control) pin. Does anyone know which of the nine Macintosh modem output pins can be used for this purpose? Secondly, does anyone know how I can change the status of this pin using MS-BASIC? -------
