# Purpose  : udev rules for the Yaesu FT-891 via the DigiRig DR-891
#
# Preconditions:
# 1. Yaesu FT-891 is selected via et-radio
# 2. Yaesu FT-891 is connected via DR-891 USB cable
#
# Postconditions:
# 1. /dev/et-cat created
# 2. /dev/et-audio created
# 3. rigctld is started
# 
# CAUTION: The FT-891 is an experimental device that may impact the stability of the platform and may
#          not work 100% of the time. This device support is best effort only.

# Special rule to ensure that the first serial interface (/dev/ttyUSB4) is tagged as ET_DEVICE=FT-891 so
# that it can be used in the next CAT control rule. The second serial device will not work (/dev/ttyUSB5)
# if it is incorrectly detected as the /dev/et-cat device.
