└─>BAYCOM ser12 halfduplex driver for AX.25
In linux kernel since version 2.6.12  
This is one of two drivers for Baycom style simple amateur radio
modems that connect to a serial interface. The driver supports the
ser12 design in half-duplex mode. This is the old driver. It is
still provided in case your serial interface chip does not work with
the full-duplex driver. This driver is deprecated. To configure
the driver, use the sethdlc utility available in the standard ax25
utilities package. For information on the modems, see
<http://www.baycom.de/> and
Documentation/networking/baycom.txt.

To compile this driver as a module, choose M here: the module
will be called baycom_ser_hdx. This is recommended.
