Drip feed DNC

Hi Scott,

I've been meaning to ask for ages...

I have a control that drip feeds line by line. It waits for a question mark response before sending the next line. Currently I use gtkterm which supports "wait for special character" before sending line and it goes line by line until the program is done. Works well enough.

It would be neat if ncplot could support this wait for char on dnc and plot it's progress during the drip feed.

Any way to make this work? Not anything I need today but a lot of older controls use this type of mdi mode and it would fill a niche.

Thanks in advance!
