Delphi How can I check the cport status? -

-

how can check cport status using comled or label displaying enabled/disabled.

i've try if cport1.connected then not satisfy me, status keeps on telling connected though not.

does here have better solution?

note: use timer check port status.

if understand question correctly,first should find ports connect device code :

procedure findports(s:tstrings); var   r:tregistry;   i:integer; begin   r:=tregistry.create(key_read);   r.rootkey:=hkey_local_machine;   if r.openkey('hardware\devicemap\serialcomm',false)   begin     r.getvaluenames(s);     i:=0  s.count-1       s[i]:=r.readstring(s[i]);   end;   r.closekey; end;
