└─>8250/16550 PCMCIA device support
In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
Say Y here to enable support for 16-bit PCMCIA serial devices,
including serial port cards, modems, and the modem functions of
multi-function Ethernet/modem cards. (PCMCIA- or PC-cards are
credit-card size devices often used with laptops.)

To compile this driver as a module, choose M here: the
module will be called serial_cs.

If unsure, say N.
