I had the same need. In Stata -display "." _continue- should work in
theory. However, my main loop was in Mata, so I included 

  print(".")
  displayflush()

where displayflush is supposed to write the output buffer immediately.
However, it seems to work line by line, so it outputs 90 dots at a time.

A compromise is to output every n-th iteration (Mata example):

  if (mod(iteration,10)==0) {
     printf("%5.0f: %7.4f\n", iteration, p)
     displayflush()
     }

Analogously in Stata:

. forvalues x = 1/100 {
.   if mod(`x',10) == 0 {
.   di "Iteration " `x'
.   }
. }
