serial driver

hi?I want to implement a RS485 driver?this driver attach on the serial driver?
my problem is how can serial driver post it received data to my RS485 driver?RS485 driver do not use the polling methods to check the serial driver has received data.

I’m not sure what you’re trying to do here:

a.) Create a RS-485 driver based on the serial driver based
b.) Create a driver to run RS-485 over serial (assuming that makes any
sense)
c.) Other
