Quatech SSP-300, SSP-200 user manual Data Rate Multiplier

		Data Rate Multiplier
Clock Mode	Max bps	Description
		Auto clock mode enables applications to request
Auto	921,600	any baud rate up to 921,600. The hardware
		drivers will select the correct clock multiplier
		based on the baud rate requested
		The X1 clock mode mimics a standard COM port.
X1	115,200	The hardware drivers lock the clock to the
		standard rate. The port will run at the baud rate
		requested by the application.
		The X2 clock mode locks the ports hardware
		clock at double the standard rate. The baud rate
X2	230,400	the port runs at will always be double the rate
		requested by the applications. This mode is
		useful for legacy applicattions which cannot
		request baud rates over 115,200
		The X4 clock mode locks the ports hardware
		clock at four times the standard rate. The baud
X4	460,800	rate the port runs at will always be four times the
		rate requested by the application. This mode is
		useful for legacy applications which cannot
		request baud rates over 115.200.
		The X8 clock mode locks the ports hardware
		clock at eight times the standard rate. The baud
X8	921,600	rate the port runs at will always be eight times the
		rate requested by the application. This mode is
		useful for legacy applications which cannot
		request baud rates over 115.200.
