Speeding up serial binding

I have a MB7060 ultrasonic sensor connected to a serial port. The sensor outputs the distance in centimeters after a capital R 10 times a second. So an output may be R091 for 91 centimeters. I have the item defined:

String Septic_Level_Sensor {serial="/dev/ttyPort3,REGEX(.*?([0-9]+).*)"}

But I am seeing junk data in the debug from the binding:

' on serial port /dev/ttyPort3b.s.internal.SerialDevice[:224]- Received message 'R091
2017-02-22 15:22:37 DEBUG o.o.b.s.internal.SerialDevice[:224]- Received message 'R' on serial port /dev/ttyPort3
2017-02-22 15:22:38 DEBUG o.o.b.s.internal.SerialDevice[:224]- Received message '' on serial port /dev/ttyPort3
2017-02-22 15:22:39 DEBUG o.o.b.s.internal.SerialDevice[:224]- Received message '9' on serial port /dev/ttyPort3
2017-02-22 15:22:39 DEBUG o.o.b.s.internal.SerialDevice[:224]- Received message '' on serial port /dev/ttyPort3

I think the issue is that the binding can’t keep up with 100 Hz messages, is there any way I can modify it to speed it up some?
