Let's assume at a certain moment there are 105 characters in the UART buffer. You read 100 (leaving 5) so LOC(#1) equals 5. It loops, and you read 100. But there are only 5 in the buffer. So it waits until it gets 100 characters, potentially eating 95 characters of the new message. INPUT$() reads upto the given number and will return immediately with whatever there is. It does NOT wait. Looping until LOC() = 0 is OK and a fast way to flush the buffer. Jim
