戴尔 dw5560 WWAN PCIE 迷你卡和 GAMMU

如何解决戴尔 dw5560 WWAN PCIE 迷你卡和 GAMMU

我有一台配备 DW5560 WWAN PCIE 迷你卡的戴尔笔记本电脑，我希望在 UBUNTU 20.04.2 上使用 gammu 对其进行监控。 gammu-detect 命令显示：

[gammu]
device = /dev/ttyACM0
name = Dell DW5560
connection = at

[gammu1]
device = /dev/ttyACM1
name = Dell DW5560
connection = at

[gammu2]
device = /dev/ttyACM2
name = Dell DW5560
connection = at

[gammu3]
device = /dev/ttyS0
name = Phone on serial port 0
connection = at

...
[gammu34]
device = /dev/ttyS9
name = Phone on serial port 9
connection = at

我尝试了以下配置：

cat /root/.gammurc
[gammu]

port = /dev/ttyACM0
model =
connection = at
synchronizetime = yes
logfile = /home/user/.cache/gammu.log
logformat = textall
use_locking =
gammuloc =

[smsd]
service = files
logfile = syslog
# Increase for debugging information
debuglevel = 0

# Paths where messages are stored
inBoxpath = /var/spool/gammu/inBox/
outBoxpath = /var/spool/gammu/outBox/
sentsmspath = /var/spool/gammu/sent/
errorsmspath = /var/spool/gammu/error/

我还尝试了一些 /dev/ttySX 路径和一个 /dev/cdc-wdm2 路径（此路径显示在网络管理器 cli 上），但仍然出现相同的错误。 但是服务一直显示错误：
