5.6 NOTES ON SERIAL DATA THROUGHPUT
The maximum serial baud rate of 921KBits/sec does not imply that
the maximum sustained throughput rate of the serial port will be as
high. The actual throughput rate that can be achieved depends on
many factors including the host PC speed, the serial data source’s
data block size and whether the block are “back-to-back”, whether
the interrupt in use on the host is being shared by other devices
leading to increased latency etc.
