Int 14 Fn 8E  - Comm-drv V14.0 - Read Packet Nondestructively              [S]

   AH = 8Eh
   CX = length of packet in bytes
   DX = port number
   ES:DI -> buffer for packet

Return: AH = line status (see #0230)
       bit 7 set on error (see AX=8000h"COMM-DRV")

Desc:  retrieve a packet from the input buffer without removing it from the

Note:  this call requires that at least the requested number of bytes are
     already present in the input buffer, and will fail if there are
     fewer bytes available
