9.If the COM port belongs to a UltraPort SI card then you can click on the Advanced button to access the software switchable interface modes as shown in the next diagram.
Protocol Type: The valid software switchable protocol types are
Baud Rate Multiplier: The baud rate multiplier allows the user to multiply the configured baud rate by 1, 2, 4, 8,16 or 32, hence achieving greater speeds on the UltraPort SI serial interfaces. This is applicable for each protocol type selected. Baud rates for
Slew Rate Limiting: The default setting for slew rate limiting is disabled. This will allow higher baud rate speeds on each EIA interface port. Slew rate limiting enabled, minimizes EMI and reduces reflections caused by improperly terminated cables. Operation in slew rate limited mode reduces the amplitudes of
Line Termination: The line termination parameter is not changeable by the user in
