Open DOS Command Window

[ssmith579]

Is it possible to open a DOS command window and send commands and parse the output? I have an application where I need to communicate to my device over Ethernet though a custom DOS program.

Here's a script I wrote a while back that would open a DOS window to run ipconfig and grab the local machine's IP address. I've not tried it lately, hopefully it still works OK on Windows 7 or later. I think this should get you started at least.

proc main
string sLine, sIP

dos "ipconfig > c:\ip.txt"
pause 3
fopen 0 "c:\ip.txt" READ TEXT
while not feof 0
fgets 0 sLine
if strfind sLine "IP Address"
strextract sIP sLine ":" 1
strreplace sIP " " ""
strreplace sIP "`n" ""
strreplace sIP "`r" ""
endif
endwhile
fclose 0
delfile "c:\ip.txt"
endproc
