The <intvar> variable can be one or more of the following values.

if result=0 then
  connect '/C=1'
  pause 3
endif

getmodemstatus val

if result=0 then
  sprintf2 str "val = %d(%x)" val val
  messagebox str "Result value"
  if val & 2 > 0 then
    ; DSR signal is enabled.
    messagebox "DSR on" "Message"
  endif
