HRM Zilog
HRM
The first CMP command compares the buffer at <2>0 with
the buffer at <1>0 for 512 bytes. The second eMP com-
mand compares the current write buffer with the current
read buffer. In this case, the write buffer is at <3>0
and the read buffer is at <2>0. 1024 bytes are com-
pared.
COMMAND: DISPLAY dseg doff dlnth
DESCRIPTION:
If NO parameters are entered:
Displays the current read buffer at <rseg>roff for
Inth bytes.
If ANY parameters are in the command string:
Displays the contents of memory at <dseg>doff for
dlnth bytes.
EXAMPLE:
RD 2 0 512
DIS?
1 0
20H
DISP
The first DISP command displays 32 (20 hex) bytes
beginning at <1>0. The second DISP displays the read
buffer at <2>0 for 512 bytes.
COMMAND: DOPKT
DESCRIPTION:
The current unit packet-status in the dispatch table is
set to GO, and WAKEUP is sent to the SMD controller.
SMDMON will
~ot
alter the packet in any way.
A packet can be set up manually with the PUTMEM com-
mand. First, the packet address is found by entering
the STATUS command, then PUTMEM is used repeatedly to
set each byte in the packet.
EXAMPLE:
DOPKT
The current unit packet is issued to the SMD controller
as is.
