INT 15h, Function AX = 01FDh: Receive Network Packet
4000API
Allows access to BIOS MAC layer for receiving network packet. Set COM
channel for proper communication rate, parity, and bits before making this call.
This system service may not be PC compatible.
On Entry:
AH = 01h
AL = 0FDh
CX = Timeout value in milliseconds
DX = COM port (0 or 1)
ES:BX = Pointer to cbuf (as in Function 1F5h)
es:[bx].len
must show number of buffer bytes available in buffer.
On Return:
DX = Undefined
AX = Undefined
CX = +length or ćerror (Function 1F5h errors)
es:[bx].adr
= Has packet destination address
(all addresses received).
es:[bx].ctl
= Has packet control character
es:[bx].buffer
= Has more packet information, if appropriate.
INT 15h, Function AX = 01FEh: Send a Network Packet
4000API
Allows access to the BIOS MAC layer for sending a network packet. Set the
COM channel for the proper communication rate, parity, and bits before making
this call.
This system service may not be PC compatible.
On Entry:
AH = 01h
AL = 0FEh
DX = COM port (0 or 1)
ES:BX = Pointer to cbuf (cbuf as in Function 1F5h)
es:[bx].len
= Length of the data to be sent.
es:[bx].adr
= Network address of this node.
es:[bx].ctl
= Packet control character.
es:[bx].buffer
= Additional packet information, if appropriate.
On Return:
AX = Undefined
CX = Undefined
