我正在尝试将minicom连接到通过USB到串行适配器连接的串行设备。这是PL2303,从我读过的所有内容来看,不需要其他驱动程序。该设备被识别为PL2303。
我是minicom的初学者。这是执行正确的命令吗?还是我需要配置一些东西?
$ sudo minicom --device /dev/ttyUSB0 minicom: cannot open /dev/ttyUSB0: No such file or directory $ sudo lsusb -v Bus 002 Device 006: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port Device Descriptor: bLength 18 bDescriptorType 1 $ tail /var/log/syslog #then removed and attached the device.

首先检查dmesg | grep tty系统是否识别您的适配器。然后尝试使用运行minicom sudo minicom -s,转到“串行端口设置”,并将第一行更改为/dev/ttyUSB0。
dmesg | grep tty
sudo minicom -s
/dev/ttyUSB0
不要忘记使用“将设置保存为dfl”将配置保存为默认设置。它在VirtualBox的Ubuntu 11.04上对我有效。
