I have a x86 QNX box and a SHT11 temperature and humidity sensor. Because the box has no I2C interface, I want to read 
the sensor data via RS232. There is a simple example using MAX233 RS232 driver / receiver. The example is http://
peterpolm.tripod.com/.

The interface board is very simple. But the software source codes link is not valid now. So I don't know how to 
implement the software. Can anyone give me some information about it?
