Methods of flow control over virtual ports

Tue Jan 20, 2009 8:22 pm

I'm currently evaluating SerialTools for use as a virtual com port.

Having looked at the vport class it seems that it has no means of performing handshaking or sending the standard control signals. How then should a 3rd Party app which is connected to the vport be told to stop sending data whilst a data backlog, or a full data buffer, is dealt with? Is the standard practice to simply allow the 3rd party app to continue sending?

Thanks in advance.

There is no traditional flow control in VPort. And yes, you should simply let the 3rd party app continue sending data.

There are mechanisms in VPorts which prevents buffer overflows.
