I'm using the Async Pro COM Port component to comunicate with a device.
If I send some commands to the device using HyperTerminal then the
device behaves correctly. If I try using the TApdComPort.PutString
method then it appears to have been successfully sent but the device
reacts as if it has not received it.
Most tellingly, if I put a break point on the PutString call, step over
it each time it is called, and the let it continue running the device
behaves correctly, which makes me think that I should be doing something
to let the device process each string I send? I've tried putting a call
to ProcessCommunications straight after the PutString call, but that
makes no difference.
The HyperTerminal settings are 4800, 8, None, 1, No Flow Control. I've
tried to match these to the TApdComPort settings, but I'm obviously
missing something.
The settings I use for the TApdComPort are:
FComDrv.Baud := 4800;
FComDrv.DataBits := 8;
FComDrv.Parity := pNone;
FComDrv.StopBits := 1;
FComDrv.HWFlowOptions := [];
Any clues?
Phil.
