Last reviewed: September 25, 1995
Article ID: Q115083

The information in this article applies to:

Microsoft Win32 Application Programming Interface (API) included with:
```
    - Microsoft Windows NT versions 3.1 and 3.5
```

SYMPTOMS

The documentation for the device control block (DCB) structure says that the EofChar field specifies the value of the character used to signal the end of the data over the communications resource. However, this setting seems to have no effect.

RESOLUTION

DCB.EofChar is not currently supported in Windows NT.

MORE INFORMATION

When DCB.EofChar is supported, you should call ClearCommError() after every read to see whether COMSTAT.fEof is set. When COMSTAT.fEof is set, this means that DCB.EofChar has been received.
