Ah, I guess both LS1 and Alloytec would be good. Look to see if the VIN function works for both, as well as if the monitor all function works with and without a filter present.

cool shall do!

Just went to test still doesn't work on xp with framework 4, did you find a reason for this?

Then went to win7 machine & connected to ls1 with J1850 VPW & then went to listen & it had an error & closed program down!
I then had the troubles again with reconnecting to elm when I restart program & yeah I tried 115200 first & then tried disconnecting & said unknown error & then when trying to choose connect on any other rate it says port already open, so restart program & choose 38400 & still can't connect unless I unplugged the elm completely from pc & power supply!

Ah, wow, have a few problems there!
The frame work is set to 3 or 3.5 so 4 should obviously be fine. Im not sure why its causing you hassle?

Damn, not sure on what cause the error for J1850 VPW, I thought I set the filter up correctly. Ill have to run it through my fake elm setup step by step to see whats happening.. although I dont exactly know what the elm does when I fire of "AT MR XX", which is the filter for monitoring the received. Ohh.. wait... Just realised the problem. The ATMR can only accept 2 characters.. Any more/less may cause issues!

As for why it doesnt work until unplugging the elm.. umm no clue again! I wont know till I get my hands on my elm device to debug issues. If you can log whats happening when you attempt to change protocols ect, that should show us what the issue is.

Hopefully this cable will pop up any time soon so I can figure out whats going on!

Nah it's worse than something simple it now fails everytime on any protocol to monitor all whether the filter is set to on or off, the only difference that makes is before it shuts down it comes up with a screen saying filter cannot be left blank & then it closes program down but if filter left unticked it just errors straight away!

Here's the log's of what I could get, it was even stopping the monitor program from listening when it had errors as the port or something musn't have been closed properly or something?

[Tazzi]

Yeah I can see some small mistakes now. Sorry for wasting any of your time VX!

41 54 46 43 53 4D 31 0D ATFCSM1.
3F 0D 0D 3E ?..>

Thats meant to reply with OK.. not a "?". I dont think that is required so Ill remove it. And ill also double check whatevers causing all these errors! Pain in the arse debugging something without the cable!

[Tazzi]

Oops, forgot to implement one last thing, Needed to do "AT FC SD 30 00 00", which I forgot to add in!.
Which out that, the AT FC SM 1 will respond with a ?.

[VX L67 Getrag]

Nah it's fine taz that's what testing is all about!

Hopefully someone else has abilities to test before I can next version!
