There is software to use the USI as a serial port here. That would be much better than any software serial library, but it can only use pins 0 and 1.Cheers,

That's clearly why PaulS thought "SoftwareSerial" could only use pins 0 and 1.
Looks a bit trickier to use though.
Generally, I use I2C for communication with tiny84 and tiny85 chips, since distances are usually short in my creations.
Still handy to be aware of what's available, though. I just downloaded the "NeoSWSerial" lib, and will give it a spin when I get a chance.
Thanks for the info.
