CAT
System Computer Control
variable in the program to an ASCII string, and
then to convert the string to characters through a
lookup table.
If you send a parameter that is out of range for
p
the intended function, or not among the speci-
b
fied legal values for that function, the FT-890
$
should do nothing. Therefore, you may wish to
1
alternate your sending regular commands or
I
i:
command groups with a
Read
Flags
or an
Update
i
command, allowing the transceiver to let the
computer know if everything sent so far has
been accepted and acted upon as expected.
Bear in mind that some commands specify
'%inary," as opposed to BCD-formatted parame-
ters. You can send binary parameters without
going through the
character/hex string conver-
sion process. For example, the CH parameter in
the Command table is binary. You could have the
PRINT $2, CHR$
(0)
;CHR$
(0)
;CHR$

;CHR$
(29)
;CHR$

;
Reading Returned Data
The reading process is easily done through a
loop, storing incoming data into an array, which
can then be processed after all expected bytes
have been read into the array. To read the meter:
FOR
1-1
TO
5
MDATA(1)
=
ASC (INPUT$
(I,
$2))
NEXT
I
Recall from above that the meter data consists
of four identical bytes, followed by a filler byte,
so we really only need to see one byte to get all
of the information this command offers. Never-
theless, we must read all five bytes (or
1,18,19 or
649, in the case of the Update data). After reading
all of the data, we can select the bytes of interest
FT-890 recall memory 29 (decimal) by the follow-
to us from the array (MDATA, in the above ex-
ing
:
ample).
