Is anyone working on a RS-485 driver? If not, I need to modify serial.c to toggle one of the control lines when the transmitter is active. I know how to do this in the code, but the process of making the module has me baffeled, make modules and make zImage don't write serial.o when I've turned off kernel support to produce a module.
Any hints? Thanks, Bill Krimmel bill@resuba.com
