RS232 Software Overview

[CDRIVE]

The RS232 Software Overview states the following:

Introduction:

These routines allow the microcontroller to send and receive RS232 data.

All functions are implemented using software, so no special hardware is required on the microcontroller. However, if the microcontroller has a hardware serial module (usually referred to as UART or USART), and the serial data lines are connected to the appropriate pins, the hardware routines should be used for smaller code, improved reliability and higher baud rates.>

Where are the "hardware routines" mentioned?

Never mind I found it. Actually I was reading something else in the help files and stumbled over it. :-)

Thanks anyway,
