- ::: To be written :::
+ Say Y here if you have a IODATA RSA-DV II/S ISA card and
+ would like to use its >115kbps speeds.
+ You will need to provide module parameter "probe_rsa", or boot-time
+ parameter 8250.probe_rsa with I/O addresses of this card then.
+
+ If you don't have such card, or if unsure, say N.
config SERIAL_8250_ACORN
