#3 Send and receive buffer

[Jungle-80]

Some companies (e.g. ICPDAS) implement their own modbus functions which are not possible to be executed via read/write registers functions.

I've looked at the source and found SendCommand function. What i would like to have is something like public SendCustomCommand function:

function SendCustomCommand(const AInputBuffer; const AInputSize: Integer; var AOutputBuffer; var AOutputSize: Integer): Boolean;

So it would send buffer, wait and receive. And it could be called from existing SendCommand function.
