Working with Docklight (Advanced)
001 CTS = High
002 DSR = High
004 DCD = High
008 RI (Ring Indicator) = High
Example Receive Sequence definitions in Decimal Edit Mode:
Receive Sequence
(Decimal Mode) Description
! | 001 triggers when CTS=high, all other signals low
! | 006 triggers when CTS=low, DSR=high, DCD=high, RI=low
! | ??? triggers on any change of the status lines
For the following example we assume that Docklight is ready to run a test as described
in
testing a serial device or a protocol implementation and Flow Control Support is set to
"Manual" in the project settings .
A) Create a new Receive Sequence for detecting handshake signal changes.
1. Open the Edit Receive Sequence dialog.
2. Switch the Edit Mode to Decimal .
3. Insert a 'signals' function character at the beginning: Press F11 , or open the context
menu using the right mouse button and choose Function character '!' (CTS/
DSR/DCD/RI changes) .
4. Add the handshake state as a decimal parameter value (see above). In our example
we want to detect when CTS is high, while all other signals are low. This means we
need to enter "001" as the parameter value, so the sequence is now:
! | 001
5. Specifiy a Comment for this sequence, e.g. "[CTS = high, DSR/DCD/RI = low]"
6. Click OK to confirm the new sequence
B) Start the test and confirm that Docklight now detects when the CTS line changes
from low to high.
Function character '^' (F12) - bitwise comparisons
The Function Character '^' can be added by pressing F12 in the Edit Receive Sequence
dialog. After the ‘^’ character, two additional character values specify which bits to check
(
mask ) and which values to expect for these bits ( value ).
Receive Sequence
(HEX Mode) Description
^ | mask | value Is a match for the next character received, when the following is
true:
((
nextCharacterReceived XOR value ) AND mask ) = 0
In other words - the ‘^’ character picks only the bits marked in
mask and compares them with the corresponding bits in value .
See below for examples.
^ | 0F | 05 Is a match, when for the next character the following is true:
Bit 0 = 1
Bit 1 = 0
