问题描述
我想存储可用的COM端口的信息并将它们存储在变量中.
I want to store the information of my available COM ports and store them on a variable.
该命令必须在脚本中运行.仅搜索，我发现此命令非常有效:
The command must run in a script. Searching only I found this command which works perfectly:
wmic path win32_pnpentity get caption /format:table| find "COM"
它返回:
USB-SERIAL CH340 (COM6)
我希望它识别哪个设备.在此信息上，我需要提取COM6或6.
Which is the device I want it to recognize. On this Information I need to extract COM6 or 6.
推荐答案
更新:这是简短版本，仅用于获取
Update: This is the more short version for to get only the part from
@echo off && setlocal enabledelayedexpansion
for /f "tokens=2delims=COM:" %%i in ('mode ^| findstr /RC:"\C\O\M[0-9*]"') do set "_com=%%i" & echo/!_com!
@echo off && setlocal enabledelayedexpansion
for /f "tokens=2delims=COM:" %%i in ('mode^|findstr /C:"COM"')do set "_com=%%i"&echo/!_com!
:: 批处理结果 ::
:: batch result ::
对于bat文件，可能建议使用 chgport 或 Reg Query
for bat file, may suggest use chgport to do this or Reg Query
通过 chgport :
By chgport:
通过使用以下变量: !_com_[%%L]! 获得 +
by using this variable: !_com_[%%L]! to get +
通过使用以下变量: %%L 获得
by using this variable: %%L to get
@echo off & setlocal enabledelayedexpansion & set "_cnt=0"
cd /d "%systemroot%"
for /f "tokens=* delims= " %%C in ('where /r . chgport.exe') do set "_chgport=%%~fC"
for /f "delims== tokens=1,2" %%i in ('!_chgport! ^| findstr /v "#"') do set /a "_cnt+=1" && set "_com_[!_cnt!]=%%i ^= %%j"
popd & echo/COM[n]: DEVICE[id]: & for /l %%L in (1 1 !_cnt!) do echo/!_com_[%%L]!
:: for get number only :: By using %%C**
for /l %%L in (1 1 !_cnt!) do for /f %%C in ('echo/!_com_[%%L]:COM^=!') do set "_com_N=%%C" & echo/ !_com_N! = COM%%C
COM[n]: DEVICE[id]:
COM3 = \Device\huawei_cdcacm_AcmSerial1
COM4 = \Device\huawei_cdcacm_AcmSerial0
3 = COM3
4 = COM4
通过 Reg Query :通过使用以下变量: !_com#! 来获取 +
By Reg Query :by using this variable: !_com#! to get +
通过使用以下变量: !_com#:COM=! 获得
by using this variable: !_com#:COM=! to get
@echo off & setlocal enabledelayedexpansion
set _key="HKEY_LOCAL_MACHINE\HARDWARE\DEVICEMAP\SERIALCOMM"
for /f "tokens=1,3 delims= " %%i in ('reg query !_key! ^| find /v "HKEY"') do (
set "_device=%%i" & set "_com#=%%j" & echo/!_com#! !_device! )
:: for get number only :: By using !_com_N:~3! to get [n]
for /f "tokens=3 delims= " %%c in ('reg query !_key! ^| find /v "HKEY"') do set "_com_N=%%c"&& echo/!_com_N:~3! = !_com_N!
COM4 \Device\huawei_cdcacm_AcmSerial0
COM3 \Device\huawei_cdcacm_AcmSerial1
4 = COM4
3 = COM3
对不起，英语不是我的母语.
Sorry, English isn’t my first language..
