The average speed of the emulated null-modem cable is 5.5 Mbytes/sec and is based on your system’s processor speed. The virtual null-modem cable affords higher data transfer rates than a traditional, physical null-modem cable.
Faster serial communication is a by-product of emulating serial interfaces.
