Given that 8N1 is supported, can we not support other modes entirely in software? 7E1, and 7O1 don't need explicit hardware support. If you need 7N1, 7M1 will simulate 7N2, which the majority of hardware will work with, (an extra stop bit). If 8N1 works, and there is confusion over support for other modes, just bit bang in 8N1 mode. -- Creamy! <3
