Can I set XonLimit and XoffLimit for serial port communication?

Hi, mhd.gar.

I´m facing the same problem you mentioned.

Any tip, please?

Tnx,

Ricardo

Its usually easier to start a new thread rather than jump into one with no activity for 7 years

What have you tried so far?

VISA "Set I/O Buffer Size" MAY help IF the hardware and the driver support it.

I do not understand your problem, I even read the old thread and still do not understand....

Anyway I just thought I would throw this out there. In my experience using Xon/Xoff for flow control only works reliably up to 9600 baud. Anything faster and you really should be using hardware handshaking like RTS/CTS.

Yes, hardware flow control is better than software flow control.

I may have last used software flow control almost 18 years ago and that was to talk to a device designed back in the 80s.

Hardware flow control is used only when the widget I am talking to requires it.

Both have become rare as computers have gotten faster. Old devices... well there is no fixing them.
