.Nm

|
|

|
exposes a
|
|

.Xr pattyd 8
|
|
|
|
|
interface as a KISS TNC via a pseudoterminal. This device can either be read
|
|
|
|
|
from or written to. The device can be connected to by only one process at a
|
|
|
|
|
time. However, multiple instances of
|
|
|
|
|
.Nm
|
|
|
|
|
can be attached to an interface simultaneously. Each frame sent out to the
|
|
|
|
|
interface, or received by the interface, is written to the KISS TNC device.
|
|
|
|
|
In turn, each frame received by the KISS TNC is sent out to the interface.

|
When a KISS TNC device is successfully created, the pseudoterminal device name
|
|
|
|
|
is printed to standard output.
