OSWORD &19 (25) - IP Network receive
This call is made by a modifed NFS to pass networking calls on to an IP networking handler. It should not be called directly by the user, programs should call OSWORD &11 and allow the networking system to forward the call to the appropriate handler.
XY?0=0 - Open receive block On entry: XY?0 = 0 XY?1 = must contain &7F XY?2 = port to receive on XY+3..4= station to receive from XY!5 = reception buffer start address XY!9 = reception buffer end address On exit: XY?0 = 0 if no more space to open blocks, or number of opened reception block. Receive blocks can be 'wild', ie will receive from anyone if the port or station values are set to &00. XY?0<>0 - Read and delete receive block On entry: XY?0 = receive block number to read XY!5 = receive buffer start address XY!9 = receive buffer end address On exit: XY?1 = flag from transmission block XY?2 = port received on XY+3..4= station received from XY!9 = updated to new address of buffer end
Unread receive blocks must be deleted with OSBYTE &34 (52).
Watford Electronics Speech control
On entry: XY!0 =address of data XY?4 =flag XY+5..6=length of data If flag is 0 then the address points to a table of byte pairs that are output as though with Speech OSBYTE &19. If flag is &8x then the address points to an ASCII string of words or allophones, terminated with <cr> or &00. The string will be spoken as with *TALK If flag is &Cx then the address points to an ASCII string of word or allophones of the length specified in the control block. Calls with flag set to &8x or &Cx, bit 3 of the flag sets the unknown word mode. If flag is &x0 unrecognised words are spoken letter by letter. If flag is &x8 unrecognised words are ignored and the call is passed to the vector at &0230.
