The SERIAL unit

The SERIAL unit is a simple interface for the first HW asynchronous interface (EUSART), without interrupts.

• It does not support a second HW port.

Demo project: None.

Features:

• Single character I/O.
• STRING output.
• The baud rate and pin setup have to be made through a BAUD() procedure call in the main program.
• The single character input procedure may be hooked to the standard READ/READLN procedures by the ASSIGN built-in procedure.
• The single character output procedure may be hooked to the standard WRITE/WRITELN procedures by the ASSIGN built-in procedure.
