Int 14/AH=0Ah

MBBIOS - WRITE BUFFER

AH = 0Ah
CX = count
ES:DI -> buffer (see #00338)

Return:
AX = status (see #00304,#00305)
CX = unsent character count
DI updated

Note: The PACCOM version of MBBIOS does not use CX or ES:DI; instead, ES contains the segment of a buffer containing the packet to be sent, which by default will be freed once the packet has been sent. Use AH=0Ch"MBBIOS" to allocate the buffer.
