Serial Problem

[veronesi]

Hi everybody,

I've got only a little question.

Is it possible to read the CTS (or DCD) status?

I found that it's possible to set the RTS status, but how to read at the receiver-end the CTS (or was it the DCD?)?

(I use a crosslink cable)

I use the UDF from this topic.

I'm very sorry for my bad english!

Thank you for your reply!

Kind Regards

At the moment my udf doesn't tell you the state of the CTS, DTR lines. I think I said in the udf thread somewhere that I could do it but so far I haven't. If it's needed then I can add a function to report the state of the various lines. I need 2 things; someone to say yes please do it, then a few weeks so that I can fit it in when it happens to be convenient for me.

Hi Martin,

thank you for your reply.

Yes, it would be a great work if you could do it!

Unfortunately I need this function very fast. But it would be great if you could ever do it!

Thank you very much!

OK, but, as I warned, it won't be fast; I have other things I must do.

Hi, I know. Thank you anyway!

    SetError(1)

@Veronesi:

Try this code. It requires NETComm OCX by Richard Grier, which is freely available on the net; download it.

You can also use $evt = $com.DSRholding(), $evt = $com.CTSholding(), and $evt = $com.CDholding() depending on your needs.

Nevertheless, I would be very happy if Martin could make it easy for us.
