Why 1.5 stop bits

The driver raises the RTS line when the "type-ahead" input buffer is less than one-half full and lowers the RTS line when the buffer is more than three-quarters full. After all buffered bytes have been sent, the RTS line will be low.

XonLim The minimum number of bytes in use allowed in the input buffer before flow control is activated to allow transmission by the sender. XoffLim The minimum number of free bytes allowed in the input buffer before flow control is activated to inhibit the sender. ByteSize The number of bits in the bytes transmitted and received. Parity The parity scheme to be used. StopBits The number of stop bits to be used. ErrorChar The value of the character used to replace bytes received with a parity error.

EofChar The value of the character used to signal the end of data. EvtChar The value of the character used to signal an event. Remarks When a DCB structure is used to configure the , the following restrictions apply to the values specified for the ByteSize and StopBits members: The number of data bits must be 5 to 8 bits.

Note Both the computer and the instrument must be configured to transmit the same number of stop bits.

Everything is done by simply counting clock cycles. Similar threads B.
