Hi,
 I need 3rd UART in my project so software UART implementation is 
obvious . I have transmitting part but does anybody has some interrupt
driven receiver site of code ( ANSI C or ASM is OK ). My baud rates 
should be bellow 19200Bd.
 Thanks radim.

Radim,

I have some 10 year old code on my website at 
http://www.moonbounce.dk/embedded.htm 
look for second last entry. 
This is code running on a Philips 87C750 type device, but (if I may 
say 
so :-) well documented, so it should be easy to port to a LPC device.
Basically it uses an external interrupt pin for the RxD, and when a 
start bit is discovered, it uses a timer to sample the individual 
bits.

Regards,
Carsten
