13 The BIOS
13.3.7 SERBaud
Default setting: auto
Parameter: baudrate The serial interface of the PTC-IIex is pre-set to the given baud
rate.
auto Automatic baud rate recognition.
Identical to the SERBaud command in the PACTOR firmware.
Sometimes it is obvious to avoid the automatically baud rate recognition of the PTC-IIex.
This is for example is the case if the PTC-IIex (the whole station) is switched on and off
by a timer. Also if you want to react the PTC-IIex on a hostmode program after switching
on you have to set the baudrate to a fixed value.
The
SERBaud
command allows the PTC-IIex to be set to a certain baud rate and to avoid
the automatic baud rate recognition after switching on the PTC-IIex and will start
directly!
To set the baud rate to 9600, just enter the following command:
cmd:
SERB
9600 <Return>
Switching on the PTC-IIex the next time 9600 baud will be displayed!
To activate the automatic baud rate recognition again enter the following command:
cmd:
SERB
auto <Return>
Switching on the PTC-IIex the next time the automatic baud rate recognition will work.
Without entering arguments the SERBaud command shows the actual baud rate. The
message “auto” will be added if the automatic baud rate recognition is turned on.
It is also possible to force the PTC-IIex to reset its
SERBaud
value to AUTO. As the
PTC-IIex has no switches to let the user express the intention to reset to AUTO, a special
procedure is used to achieve this.
The PTC-IIex performs a LED test when powered on. This test has 2 phases, first the
LED´s are red and afterwards they appear green. When the PTC-IIex is switched OFF
again whilest in the first LED phase (red), then at next power up it will come in
AUTObaud condition.
Some experience may be necessary to hit the right moment for switching off. If it does
not work the first time just try it again.
Remark: When switched off whilst the second LED test phase (green) the BIOS is
activated (refer to 13.2 on page 161 ). Being in the BIOS the PTC-IIex indicates by only
lighting the green Connected LED.
13.3.8 SYStest
Switches to the
SYStest
commands. The command prompt changes from
cmd:
to
sys:
.
