Compatibility Options
Virtual Serial Port Tools provides different compatibility options that can be configured to change the behavior of virtual serial port driver.
Currently, the following compatibility options are supported (see also ISerialPortLibrary.compatibilityFlags):
| Value | Description |
|---|---|
| Ignore invalid special characters | Virtual serial ports must silently ignore invalid special characters set by application. By default, when this compatibility flag is not set, virtual serial ports fail requests that attempt to set invalid combination of special characters, as required by specification. |
| Ignore transmit queue clear purge requests | Virtual serial devices will ignore serial purge requests with TXCLEAR flag. This prevents unwanted behavior if the request is erroneously sent by application while there is still data in transmit queue. Currently applies to local bridges only. |
