Function COMAllocateBuffers

COMAllocateBuffers allocates send and receive buffers for a port:

void COMAllocateBuffers(int      Port, 
                        unsigned ReceiveBufferSize, 
                        unsigned SendBufferSize);

Parameters

Port

The port to configure.

ReceiveBuffersize

The receive buffer size in bytes.

SendBuffersize

The send buffer size in bytes.

If the buffers have been allocated already, this call has no effect. The call to this function is not mandatory; function COMEnableInterrupt will call

COMAllocateBuffers(Port, BufferSize, BufferSize)

to ensure that buffers are available.
