RGH | See cover!
I have here (in the firm) PCs with a seriellen Port on COM1. I should for a Program somehow check whether a serielles unit on these interface angestöpselt is, circa in the program with are missing the Gerätes defined Options auszublenden. has someone a idea? (In XProfan; Delphi goes but too.)
Greeting

E.T. | Huch  , Roland has 'ne question ... Joke ??
in the serious: on the COM-Port can Yes not plenty read, what a unit concerns. If, How I your question entnehme, the COM-Port famous is and, which unit drann stick should, would I simply whom COM-Port inquire (with for unit known Settings for Baud / Parity etc.) and on a response hoping.
ought to a response arrive, is Schonmal one unit on the COM angestöpselt. then The response evaluate, if The data so looks How expects, isses ok. If unerwarteter "Daten - Müll" or nothing ankommt, is hold nothing angestöpselt or one other unit, what on inquire not reacted or unsinnige data supply.
so would I rantasten .... |

H.Brill | usually should still one unit
the DTR signal ((Data terminal Ready)
settle, if it connected becomes.
Perhaps can this somehow inquire.
on can something like Yes with SetComExt(). |
