Comunicação serial WvDial não funciona com uart / dev / ttySAC4, mas funciona com 'screen'

1

Eu tenho um sistema embarcado baseado na placa Samsung Artik 710 conectada ao módulo de modem celular Fibocom G510 via UART (duas linhas - RX e TX).

Quando tento me comunicar com o modem usando screen - o modem responde aos comandos AT e parece que está funcionando:

$ screen /dev/ttySAC4

.

AT
OK
AT+CGDCONT=1,"ip","playmetric"
OK
ATDT*99***1#
CONNECT
}&} } } } }#}$ďż˝#}%}&ďż˝}"Ú}'}"}(}"��

(...)

Quando eu tento com wvdial - parece que não há comunicação serial.
