What happens to a string after it is written in serial port using fprintf?

What will happen if a string is written to a serial port using fprintf? Does the string stays in the serial port unless deleted/flushed? Thanks for answering!

It disappears down the serial connection when transmitted...when/how that happens depends on how the port/connection is configured.

Thanks for answering! But what do you mean with "depends on how the port/connection is configured"? Can you site examples?

Basically, the state of handshaking between the devices...hardware or software controlled.
