The start bit is low, i.e. the same polarity as a zero data bit, which is + voltage on the RS-232 line due to the inverting line driver. If you use an inverting line receiver (most are), then the start bit is low again. If you are reading the line directly, look for positive voltage. The bits come over in LSB first order: the first data bit after the start bit is the LSB. The parity bit, if any, is after the last (MSB) data bit and before the stop bit. The duration of each bit, including the start and stop bits, is 1/baud rate, or 104.17 us for 9600 baud. There is no time space in between bits. > > _____________________________________________________________________ You don't need to buy Internet access to use free Internet e-mail.
