Ok, I'm thinking about switching my power supply to a couple of 4 volt Wheat open-faced wet-cells (for 8v total) and have some questions to ask before frying my hardware. I believe the rs232 spec says that a zero is -12 to -3 volts, nothing is -3 to +3 volts, and one is +3 to +12 volts, right? So, afaik, the only thing that I'm using +12 and -12 from the ISA bus is for the serial UARTs. Will they get mad an maybe even die if I replace the +12 with +8 from the batteries, and replace -12 with -7 via an op-amp wired as a charge-pump thingie? This would fall within the rs232 limits... ____________________________________________________________________ Get free e-mail and a permanent address at http://www.netaddress.com/?N=1 -- Subcription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" toWear-Hard Mailing List Archive (searchable): http://wearables.blu.org
