Return Values

Return Value Description
N Command Recognised but Invalid data entered.
? Command Not Understood
[command] Command Accepted

Often entering a text command by itself or followed by the first paramater
will return the present value of the setting.

Generally paramters have

0 1
State Off ON
Cannel (Band) A B

It may be able to tell if the unit attached has SkyCommand II by requesting
the SkyCommand Call Sign. If the SkyCommand II is not available in the model,
an error should be returned.

The most useful command is “AI 1”. It sets the TH-D7 to transmoit out the
serial port information about what the radio is doing. A ‘Y’ in the third
column indicates that the radio will send this string out the serial port
when it is varied.

Command Description
ABC [0|1] Automatic Band Change [D-700]
ABLG APRS BLN Group
AMGG APRS MSG Group
AMR [0|1] APRS auto msg reply
AD [0|1] Auto Display Dim [D-700]
AI [0|1] Turns on output functions. Immediate functions output to the PC serial
port.
AIP [0|1] Turns of Advanced Intercept Point – 1=On
APO [0-2],n Auto Power Off, 0=Off, 1 = 30 min, 2 = 60min APO *returns* two arguments,
the first being the current APO setting and the second set to 1 if the unit
is about to be powered off. I.e. if you adjust it, you’d send/receive “APO
n,0” where n is the setting, but if you let it sit for 30 minutes or whatever,
the D7 will start beeping and send “APO n,1” where n is the current setting.
APO returns 0 if APO is disabled. Returns APO1,0 when enabled.
ARL nnnn Pos Limit (nnnn=km, 0000=off)
AMSG [01-16] Lets you view the corresponding APRS message with theresulting format

AMSG a,KD6VYV-7,MESSAGE CONTENT HERE,b
format of “a”

a = number 1-5 then a= number of
transmission left for message.

a=* acknowledge received from
receiving station (your message sent and received)

a=M Mine – this makes me think
that there might be B for bulletin, !,etc.

format of “b”

b is an unknown number and can
be either one or three characters in length).

AMSG [00] Lets you enter a new APRS message with the format:

D700 allows you to have multple “my position” stored (1-5):

MR [0],[0],nnn Reads memory nnn. nnn may be in the form 018, or L7Returns a MR string of the same form of BUF above, or form below.

The absolute last parameter is a 0/1,   1 being memory lockoutThe second parameter is used to store a split frequency.  For

example, if you store a frequency of 145.00 rcv, 145.30 xmt in

channel 20, you get the following:

MR 0,0,020,00145000000,0,0,0,0,0,,09,,09,,0,0
