6402 UART
Bogdanfirst I have given up with the MC14034 as it requires too much support logic.
The FUART from www.chipcenter.com is a bit of code that can be written to a PLA or similar - not a component - doesn't seem a viable option. As I see it there are now two options (soon there will only be one ...) [1] program a microcontroller (could be done and could achieve additional coding/decoding/control) but if you aren't geared up to write and program it could be daunting. [2] I have found a supplier with a limited stock of 6402 UARTs (UK price around £9). This could be the easiest option as there is no debugging of code and will require little more than an RC oscillator (remember a full circuit is required at both ends of the line. http://www.viewcom.force9.co.uk/data/ic5.htm (8 lines from the bottom of the page).
