我有一個批處理文件,我想發送命令到串口COM1。我有以下,我可以看到它正確設置端口。但是,它在設置串口後停止,它不發送任何命令。批處理文件不發送串行命令
@ echo off
color b0
cls
echo.
echo.
echo. Enter IP address of the CSR on the site.
echo. Example: 11.152.34.82
set /p IP="IP Address: "
for /F "tokens=1,2,3,4 delims=." %%a in ("%IP%") do (
echo %%a, %%b, %%c, %%d
set last=%%d
set first=%%a
set second=%%b
set third=%%c
)
pause
cls
echo. select the technology you are trying to restore
echo. 1: AWS
echo. 2: PCS
echo. 3: LTE 1
echo. 4: LTE 2
set /p tech="Enter number: "
if "%tech%"=="1" goto AWS
if "%tech%"=="2" goto PCS
if "%tech%"=="3" goto LTE1
if "%tech%"=="4" goto LTE2
echo. Not found
goto commonexit
:AWS
set /a z=%last% - 2
set /a y=%last% - 25
goto UMTSScript
:PCS
set /a z=%last% -3
set /a y=%last% - 24
goto UMTSScript
:UMTSScript
mode COM1 BAUD=9600 Parity=n DATA=8
echo. command1 > COM1
echo. command2 > COM1
也許命令不明白,因爲它的前面有一個空格?嘗試使用'echo command1> COM1'而不是'echo.'。 – soja
試試看:'set/p「= COMMAND1」 \\。\ COM1' –
