Other Points.____________
NewBIOS ignores calls to ports whose address is zero. If
the device driver has not been installed, that is if NewBIOS has
been installed alone, then the buffer status is returned as for a
closed port, a halted, zero-byte long buffer.
Note The EASYC.C program contains sample C source code
to write directly into the buffers and demonstrates the
use of kickstart.
