Jaime,

Use EscapeComm under Win16.
Use EscapeCommFunction under Win32.

Jamie!

That functions let me set or clear, for example, DTR and RTS signals. That isn't what I wanted to do. I want to know in what state (high or low, 1 or 0) is the signals CTS and DSR. Under win32 I used GetCommModemStatus. But it isn't supported by Win16.<br />
<br />
Thanks<br />
Jaime<br />

Hi all genius. I have programmed a program in Windows 95 that uses serial ports. Under that platform, I used GetModemCommStatus to get the status of Clear To Send and Data Set Ready lines of RS-232. That function doesn't exist in 16 bits Windows. How can I do the same in Windows 3.1? I've used GetCommError but this doesn't work :(<br />
<br />
Thanks in advance,<br />

How to get status of serial lines (CTS, DSR) with Windows 3.1 Communications API

Most development for the Microsoft platform is done utilizing the technologies supported by the.NET framework. Other development is done using Visual Basic for Applications (VBA) for programs like Access, Excel, Word and Outlook, with PowerShell for scripting, or with SQL for large databases.
