Int 14/AH=0Bh

MBBIOS - READ BUFFER

AH = 0Bh
CX = size of buffer
ES:DI -> buffer

Return:
AH = composite line status (see #00304) formed by ORing all statuses
on receive interrupts; bit 0 set if additional characters
available
AL = composite modem status (see #00305) formed by ORing all statuses
CX = number of characters actually read
DI updated

Note: The PACCOM version of MBBIOS does not use CX or ES:DI on call, instead returning ES set to the segment of the buffer containing a received packet, or 0000h if no packets available; the buffer may be freed with AH=0Ch"MBBIOS"
