MP (8-bit Direct Menu Parameter Access; GET/SET)
SET/RSP format: MPnnn; where the useful range of nnn is determined by the present menu entry (255 max, or 8
bits). Only menu entries marked with ‡ in Table 5 or 6 can be accessed with MP, while others will return “?;” (use
UP / DN, DS, and SWT/SWH in such cases). There is also no range checking with MP in most cases, so the user’s
macro or application must verify the correct range.
Details: MN (described above) accesses menu entries. MP can then be used (in some cases) to read or set the
parameter value. (In some cases, more than one value can be accessed for a given menu entry via the numeric keys;
see menu listing in manual.)
To determine a numeric menu entry’s parameter values (nnn): First, go into the menu manually and set the
parameter to specific values of interest. Then type “MP;” in the command test box at the top of the Command
Tester screen to see the associated nnn value.
MP Command Special Cases (KX3): For the menu entries listed below, the MP get/set value pertains only to
specific binary bit fields in the 8-bit quantity. (For MP SETs, the KX3 protects all unrelated bit positions, so the
application can’t inadvertently modify them. For MP GETs, the KX3 masks off unused bit positions, so they will
always return zero.) Where a single bit is specified in the list below, the values x/y are associated with bit values of
0/1. Example: To select iambic mode B for CW mode, first send MN001; (to select the CW IAMB menu entry),
then send MP128; (since 2^7 is 128, this sets bit 7 of the parameter). To select iambic mode A, instead, send
MN000; (clearing bit 7; the other bits are unaffected because of the masking mentioned previously). To read the
current value, send MP; and look at only the value of bit 7 in the return parameter. The response would be either
MP000; (mode A) or MP128; (mode B).
