After your patch i got further :-)

with

echo hello23 | jsr -v -v vcan0:20,3333 30

i got with candump this:

vcan0  18333020  [8] 68 65 6C 6C 6F 32 33 0A

i got with 'jsr vcan0:30' this:

hell

i got with 'jspy -P' this:

vcan0:20,03300 30 !6 [8] 68656c6c 6f32330a

where i don't know if the output from 'jsr vcan0:30' is correct ?!?

When extending the payload data with

'echo hello234 | jsr -v -v vcan0:20,3333 30'

'candump -td' tells me:
 (022.199332)  vcan0  18EC3020  [8] 10 09 00 02 02 00 33 00
 (000.000046)  vcan0  18EC2030  [8] 11 02 01 FF FF 00 33 00
 (000.000034)  vcan0  18EB3020  [8] 01 68 65 6C 6C 6F 32 33
 (000.000008)  vcan0  18EB3020  [3] 02 34 0A
 (000.000055)  vcan0  18EC2030  [8] 13 09 00 02 FF 00 33 00

with 'jspy -P' :
vcan0:20,03300 30 !6 [9] 68656c6c 6f323334 0a

But with 'jsr vcan0:30' i still got this:
hell

---

The questions:

1. Is the behaviour of 'jsr vcan0:30' correct like this?
2. Can you tell me, what's going on the second candump?

I expected something like this BAM
 (628.395620)  vcan0  18ECFF20  [8] 20 09 00 02 FF 00 33 00
 (000.050093)  vcan0  18EBFF20  [8] 01 68 65 6C 6C 6F 32 33
 (000.050091)  vcan0  18EBFF20  [3] 02 34 0A

which i got, when invoking 'echo hello234 | jsr -v -v vcan0:20,3333' (without
giving an explicite destination address).

Regards,
Oliver
