10 Hostmode
145
The parameter of the
%M
command activates the respective hostmode terminal expansion.
At a hostmode start, it is always set to 0. (The hostmode program must choose the
respective amount of expansion it needs for itself after the start. This greatly eases step by
step software expansion).
If a too high value is chosen, (that cannot be interpreted by the PTC due perhaps to an
older firmware version), the PTC answers with an error message (code byte=2) which
contains the maximum possible argument value.
%M
0 - Switches the hostmode terminal expansion off.
(This command is normally not needed by the terminal program, as the
%M
parameter is
automatically set to 0 at hostmode start.)
%M
1-
delayed echo
is output with Code-byte=8.
(With PR up until now, even with
%M
1, no "delayed-echo" has been given, as this
function is better done over the monitor channel data stream which can even handle self
sent packets.)
Note: Code byte 8 is not defined in
WA8DED
-hostmode, and is used to define a special
extension of the PTC-IIIusb. Terminal programs which wish to work with the
delayed
echo
in hostmode, must logically be appropriately extended to contain this feature, and
choose the extension required automatically. Manual switching of the hostmode
expansion is not to be recommended due to possible incompatibilities.
10.4.33
%O
Performs a CHANGEOVER. This command can also be used in the receiving condition
(
IRS
). In this case, it leads to a BREAKIN.
During transmission (
ISS
), the
%O
will be executed when all characters in the
transmission buffer are completely sent and confirmed.
10.4.34
%Q
%Q basically has the same function as %O (over command), i.e. it puts an “over token”
to the end of the PACTOR transmit buffer triggering and “over” from ISS to IRS state
after all transmit data has been sent. In contrast to %O, the %Q command does not cause
a “breakin” (“over” from IRS to ISS state) if the PTC currently is in the receiving state
(IRS).
10.4.35
%T
Displays the total number of bytes that have been sent and confirmed in PACTOR so far.
The value is reset at the end of each connection. The number can also be reset by giving
an argument behind the
%T
command. The format is identical with the standard decimal
ASCII output as used in the hostmode.
10.4.36
%V
Displays a short ASCII string containing the actual version number of the actual version
number of the PTC-IIIusb firmware and the actual version number of the PTC-IIIusb
BIOS.
