08 to 18x serial problems

I'm using a 08 with a ultrasonic rangefinder. The figure is error checked to be no greater than 20. This figure is then sent using the serout command to an 18x. When debugged on the 08, the figure is stable but when debugged on the 18x it jumps about a lot. At the moment I have a 10k resistor pulling the input to ground. Any ideas on making it more stable?

Yes. Try putting a cap from resistor at Picaxe, up to Power Rail. This will charge cap through 10k. Then when 18X is triggered will discharge quickly but should stay more stable for you. Worth a try anyway.
