receiving characters

Can the serial in buffer get purged when read?

In a Pic, for example, the receive buffer is three deep and gets emptied as it is read.

In RR, while it's easy enough to send a character once and mark as sent, I have no indication that the serial is read. How do I do this?

Is there any 'clear on read'? At the moment I don't know if I've read the value, or if the same value has come in again as a new string.
