Yep, and that isn't possible with WinXP. Mach3 runs a buffered
interface to the Smoothstepper. I think there is about 100 ms of
buffered data at anyone time.
WinXP is pretty much antique software. Win7 support goes away in
January. Not that I'm all that concerned about Windows support.
But drivers will begin to be a problem soon for Win7 as manufacturers
drop support for the software.

Trying to dual boot WinXP and Linux is a waste of time.
Get another computer if you want to play with both.
The entire Mach3 vs LinuxCNC thing is a dead subject. Mach3 runs on
obsolete software only. Its a dead end product. WinXP might as well be
DOS. Mach4 is unknown to me and requires a phone home license. Is
there a compelling reason to go there? I don't know of one.
Windows 10 compatibility is nice, but just having Windows 10 is a double
edge sword. They update it when they want, and the user has little
control of the OS updates.
Regarding the command line thing:
I've got a customer who has been running an automated Waterjet CNC
machine ( conveyor input sheet feeder ), automatic squaring, etc for
over 10 years now. No one in the plant knows anything about the
"command line" or even what that means. If I called them and told them
to pull up a command line, they would have no idea what I was talking
about. They load the program, enter the number of sheets to cut and hit
the start button. And this is all running on an old version of
LinuxCNC. I've set them up with spare PCs equipped with SSDs. The last
failure was 5+ years ago. The PC hardware runs 24x7. I visit that
plant about once a year to fix something, otherwise their machine runs
with just normal maintenance.
LinuxCNC; Whats not to like? :-)
