enabled. Flow control is generally faster and permits the receiver to operate at
its peak capacity.
Another factor in performance is the presence of other software running in the
background. Card and Socket Services, for instance, use the timer interrupt for
certain functions. Because Card and Socket Services chain into this interrupt
and execute some code with interrupts disabled, the system may become
overburdened when running serial interrupts at high speed (greater than 19200
baud). In this case, overrun, parity, and framing errors become more common,
sometimes resulting in an inability to send a file efficiently. If this occurs, select
a lower baud rate (refer to
) and enable flow control (refer to
