The Readme does state how you do this. Search for command and you will find it in the readme

The readme states how to send command line parameters to DOSBOX or to send a DOS command. I need the parameter sent to the DOS program itself.

dosbox "C:\DOSDIR\DOSPROGRAM.EXE" -exit -conf "C:\DOSDIR\DOSPROGRAM.CONF" -noconsole

This is an example of the shortcut icon Target command line. When I execute as above, it works great. But when I add the parameter "/com=3" to be passed to DOSPROGRAM, it aborts and just brings up the DOSBOX console.

dosbox "C:\DOSDIR\DOSPROGRAM.EXE /com=3" -exit -conf "C:\DOSDIR\DOSPROGRAM.CONF" -noconsole

I've tried the -c command parameter, and many combinations and arrangements.

Thank you

How did you try the -c command?
And if that fails why don't you use the autoexec section of the conf when you already pass that along (instead of executing the program with dosbox)?
And most importantly, does the program work inside dosbox with the /com3 command?

The AUTOEXEC section worked. I didn't know that you could use that section to run the final program. The order of execution between AUTOEXEC and the command line parameters was confusing.

My commands in the Autoexec section are:
MOUNT C "C:\DOSPROGRAM"
C:
DOSPROGRAM /COM=4
EXIT

I found that the -noconsole parameter had to be left on the command line. I couldn't get it to work from within the conf file.

Otherwise, I'm 100% up and running. Thanks for your help!

you're welcome. The -noconsole switch is needed for the command line because it needs to be set right away, when Dosbox reads the conf file it is already too late 😀
