串行端口名稱不能在終端和喜好系統

Question

一樣，我能看到在終端串口：

ls /dev/tty.*

也OSX：優先系統 - >網絡。

但名稱不同，例如：/dev/tty.usbserial-26223B和四RS232-HS 24

我有64個端口，所以我不知道至極一個是好一個......

Answer 1

串口應該都有對應的/dev/cu.*設備（Call-Up）。如果您正在尋找通過USB連接的特定設備，也許您最簡單的路線是檢查/dev設備斷開連接，然後連接並再次檢查。

您還可以使用system_profiler來查找有關使用/dev/tty.*設備的信息，例如，運行system_profiler 2>&1 | tee system.profiler.log和搜索/dev/tty我看到：

| +-o IOSerialBSDClient <class IOSerialBSDClient, id 0x100000471, registered, matched, active, busy 0 (0 ms), retain 5> 
|  { 
|   "IOClass" = "IOSerialBSDClient" 
|   "CFBundleIdentifier" = "com.apple.iokit.IOSerialFamily" 
|   "IOProviderClass" = "IOSerialStreamSync" 
|   "IOTTYBaseName" = "Bluetooth-Modem" 
|   "IOSerialBSDClientType" = "IOModemSerialStream" 
|   "IOProbeScore" = 0x3e8 
|   "IOCalloutDevice" = "/dev/cu.Bluetooth-Modem" 
|   "IODialinDevice" = "/dev/tty.Bluetooth-Modem" 
|   "IOMatchCategory" = "IODefaultMatchCategory" 
|   "IOTTYDevice" = "Bluetooth-Modem" 
|   "IOResourceMatch" = "IOBSD" 
|   "IOGeneralInterest" = "IOCommand is not serializable" 
|   "IOTTYSuffix" = "" 
|  } 

但是，網絡信息是分開的，這相當於你的喜好GUI看到：
