[wheel]

Вот так?
[global]
Nice = -15
LogFile = log
#LogFile = /dev/tty
ClientTimeout = 5
LogFile = stdout
globo = 1

[serial]
Device = tuner1 @/dev/ttyS0?delay=1&timeout=600

[serial]
Device = tuner2 @/dev/ttyS6?delay=1&timeout=600

# Golden Interstar
#Device = gi://tuner@/dev/ttyS0

# General Satellite
#Device = gs://tuner@/dev/ttyS0
Этот параметр ускорит оба тюнера или один?
