Message-ID: <137@looking.UUCP> Date: Mon, 19-Mar-84 00:00:00 EST Article-I.D.: looking.137 Posted: Mon Mar 19 00:00:00 1984 Date-Received: Mon, 19-Mar-84 07:30:30 EST Organization: Looking Glass Software, Waterloo, Ont Lines: 18 I wonder if it might be a good idea for 212 manufacturers to include a 2400 baud, half duplex option on intelligent modems? I am sure a lot of people would be willing to buy them. It could be done two ways. The first way would be like 202, where the modem would transmit at 2400 baud (one modem xmit on both carriers, other receives on both) and a special signal from the receiver - like a break, but perhaps a special code in the sync bit pattern - would reverse the direction. A simpler method is just to have the sender and receiver agree when to switch. This is of use only for data communications like uucp. Assuming the switches could be done fast enough (or we had a different program) we could get 2400 baud out of the existing equipment. Anybody who's uucp phone bill was $100 a month would save $50 a month, and that is about all these additions would cost. -- Brad Templeton - Waterloo, Ontario (519) 886-7304
