how to get applications which enable blinking to work in vDOS
Run DOS applications in Windows.

I'm getting past one hurdle at a time on this...right now I have the application Clarion Personal Developer working, however it makes use of blinking colores. How would I get blinking to work...do I have to install an ANSI driver, such as ANSIPLUS?
Thanks,
Steve

Blinking isn’t supported by vDos, so you have to do without.

I meant to ask if a 3rd party ANSI driver can make it work or if it's something that has to do with the video portion of the emulator that prevents it from working.
Blinking is (was) done by the video card in a text mode configuration by setting the high bit of the background color attribute of a character cell (so you lost 8 of the 16 background colors in that mode).
The video card is in graphics mode in Windows, so there’s no hardware blinking available. It would have to be emulated in software, just like a blinking cursor. Since there’s no interest for (annoying) blinking, it’s no supported.
An ANSI driver is built in vDos, but w/o the simulated video card support of blinking, it won’t help. Furthermore the ANSI driver mainly provides for an alternative method to set colors, mouse position etc., instead of using the BIOS or direct hardware access. It’s mostly used by some ancient DOS programs and extending the output of DOS commands (echo).
