The Character DDK currently includes the source code for the 8250 serial
driver. You may not have to change much:
- If your serial hardware is completely compatible with the 8250, you might
not have to change anything.
- If your hardware is almost compatible with the 8250, you might
have to change the register addresses.
See
"Registers,"
below.
- If compatibility is in question, you may have to change the source code.
