Follow these steps:
•
Choose 1 or 0 for each bit in the flag byte. Read the descriptions for each
bit carefully to decide whether to enable or disable each bit.
•
Convert the bytes to hexadecimal numbers. The resulting two hex
numbers are the value you will specify (in Step 3) to restore the UART
FIFO control register.
For example, a two-digit value of 81 enables UART 16x550 mode, requires
the buffer to receive four bytes of data before generating a receive interrupt,
and leaves all other parameters disabled.

3. Specify the value for the UART FIFO control register using one of these
methods:
• Start the configuration application (IC.EXE), choose the COM port from
the COM menu, and type the value into the FIFO CONTROL
REGISTER parameter. For help using IC.EXE, see Chapter 4,
“Configuring the JANUS 2050.”
• Scan the Communications Port, UART Restore command in Chapter 10,
“Configuration Commands.”
• Use software interrupts. For help, see the JANUS PSK reference manual
set.
