6 Commands
6.92 SYStest
The system test is not normally required by the PTC user, but has been included here
for the sake of completeness.
SYStest
is purely a tool to diagnose and rectify faults
in defective PTCs'. In normal operation this function is not needed.
The command
SYStest
(without argument) activates the system-test menu. (
sys:-
menu). The command prompt takes the form sys: .
Within the
sys:-
menu the following systemtest commands are allowed:
Audio
,
Beep
,
DD
,
Down
,
Fsk
,
Help
,
Kill
,
Led
,
Ptt
,
PLl
,
Ram
,
Up
,
Quit
.
All other normal commands are not available! The sys:- menu is ended with
Quit
or
DD
.
The
SYStest
command may also be followed by an argument which should be a
command from the
sys:-
menu. In this case, the PTC carries out only that given
systemtest command, without switching to the sys:- menu. The command virtually has
been fed through.
This command for example would show the PTC-IIex RAM expansion.
cmd:
SYS
Ram <Return>
For a detailed description of the SYStest commands see chapter 12 , page 156 .
6.93 Term
Default setting: 0
Parameter: 0 Simple terminal mode.
1 Terminal mode with delayed echo.
2 Split screen terminal mode.
3 Enhanced split screen.
4 Split screen with command prompt recognition.
5 Split screen also for Packet-Radio.
With this command it is possible to make the PTC-IIex support split screen terminals.
In simple terminal mode text is not sent to the terminal when the PTC receives
commands from the user. The text stream is interrupted by the first command given to the
PTC. At maximum 2000 characters are stored. The terminal must have local echo
(halfduplex).
Terminal mode 1 is for use with simple split screen terminals. The incoming text, and
the text to be sent out, should be displayed in separate windows on the screen. All
transmitted characters are echoed by the PTC, as soon as they are transmitted and
correctly confirmed by the station the PTC is connected to (delayed echo).
In terminal mode 2 the PTC completely controls the switchover between the windows
on the screen. Therefore the screen is divided in two areas. In the upper area the system
information of the PTC and the text to be transmitted appears. The lower window shows
the received text and the delayed echo-text. The PTC sends Ctrl-A as a changeover
