TurboPower Sync TAdpComport component

[Tremorblue]

Hi,

I have been using this component for a while to do
serial communications.

Can anyone explain or show how to switch on RTS/CTS hardware handshaking.

Thanks.

Look at the HWFlowOptions. I'm looking at the Delphi instructions for an example so it may be missing something in the translation:

ApdComPort->HWFlowOptions = [hwfUseRTS, hwfRequireCTS];

I use the equivalent instructions in Builder.

The hardware handshaking doesnt seem to be working. I am trying to talk to an old embedded device that has a small comms buffer and frequently wants to pause comms as its buffer is full.

I have a scope setup and with other software I see the handshaking lines going up and down, with the comms stopping when it should. With this component nothing seems to happen ?

Have you seen it work live ?

Thanks.

I've never used hardware handshaking, just XON/XOFF with Asynch. I use Asynch's triggers in similar sitiations. Have you tried them?
