Why do you need such small buffers? Surely your computer has hundreds of megabytes maybe even gigabytes of memory so why fiddle about with 'byte' sized buffers. Bigger buffers reduce processing overhead and reduce chances of buffer overflow.
On the other hand if you really need MSComm32 behavior then you'd need to stick with MSComm32

A modern version of Windows is handling 100's of separate tasks. Some display adapters can even disable serial port IRQ for small periods of time.
I assume the guys at SComm just think that any InBufferSize smaller than 4096 is unsafe and, as previous 'guest' said. Your PC has more than enough memory so that size buffer is not going to cause you any problems.
