AVR USART by software?

[MrMikey83]

Without buying new controllers, I have two controllers I can use for a project. I have ATmega32's and ATtiny11's.
The project is to turn my cars cruise control buttons into iPod play controls. The buttons will connect to the controller which when pressed will send a serial command and button release to the iPod through the dock connector.
I don't want to use a huge ATmega32 for a 3 input project but the ATtiny11's dont have a built in USART.
Is there a way to do this with software through an output?

Don't do AVR, so I can't give you code, but it's TRIVIAL on a PIC, or any processor - so I'm sure it will be trivial on an AVR as well!. The extremely old Commodore VIC20 used a software UART back in the very early days of home computers!.
