Serial Port

[jjj]

Does anyone have a UDF for serial port i/o? What I want to do is set a pin to high or low, and read to see if a different pin is high or low, for use with simple relays.

I am wondering about a udf because i have no idea how to program with dll calls.

Any help would be appreciated!!!

If AutoIt uses the Win32 API for it's FileOpen and FileRead calls, then you can use these functions for serial communication.

I said IF!

I have an application for this. Can anyone point me in the right direction to read if a pin is high/low?

If you want to know the states of one of theses lines

- CTS (Clear To Send) signal

- DSR (Data Set Ready) signal

- RI (ring indicator) signal

- RLSD (Receive Line Signal Detect) signal

then I have a function _CommGetLineStates in my serial port udf, shown in my signature, which returns the current state (ON or OFF) of each one.

If it's not one of those lines then I don't know.

EDIT: First said I could add the function but then found I had already done it.
