the data. The process of checking the bit until it goes high followed by a write is repeated until no data
remains.
The following C code fragment demonstrates this process:
outportb(BA4, inportb(BA4)|0x02);
/*Set RTS bit without altering states of other bits*/
while(data[i]);
/*While there is data to send*/
{
while(!(inportb(BA5)&0x20));
/*Wait until transmitter is empty*/
outportb(BASEADDR,data[i]);
i++;
}
outportb(BA4, inportb(BA4)&0xFD);
/*Reset RTS bit without altering states of other bits*/
