When I receive data over VCOM serial port the maximum size of the one transaction is below 4kB. Tested on Ubuntu and Debian. Probably it is internal buffer problem. Is there any way (except writing new drivers) to make them larger.



On Windows I can receive 8kB without any problem in one read. On Linux I need to read smaller chunks.
