Syntax:
Parameters:
Returns:
Function:
value = getc()
value = fgetc(stream)
value=getch()
value=getchar()
stream is a stream identifier (a constant byte)
An 8 bit character
This function waits for a character to come in over the RS232 RCV pin and returns the
character. If you do not want to hang forever waiting for an incoming character use
kbhit() to test for a character available. If a built-in USART is used the hardware can
buffer 3 characters otherwise GETC must be active while the character is being
received by the PIC®.
If fgetc() is used then the specified stream is used where getc() defaults to STDIN (the
last USE RS232).
