Dynamic reconfiguration of UART polling loop with a jump table

In a system for servicing a plurality of Universal Asynchronous Receiver-Transmitters (UARTs) using a polling loop, each UART having a receive function and a transmit function and also having a dynamic servicing requirement, a method of optimizing data throughput comprising:

• a) causing the polling loop to select current UARTs in such a manner whereby each UART is eventually selected as the current UART;
• b) providing a first jump table having one entry for each UART served by the system, each entry pointing to a routine for servicing the entry's UART according its servicing requirements;
• c) executing the routines pointed to by the first jump table entry for the selected current UART;
• and
• d) modifying the entries in the first jump table when the dynamic servicing requirements of the UARTs change.
