DGA 5000 Snap on gas machine unconnectable do you own one

Who's fault is it though? I remember going back to the 1990's when SUN sold the DGA 1800. I bought it brand new and a week or so later VOSA came round with SN telling everyone AE that our gas analyzers must be tested through the serial port for communication purposes to connect it to VOSA future database that never materised, at a unnecessary cost of £90 plus vat as I remember, and we could not charge vat on the mot's either. Now my DGA 1800 was a few days old from the factory and I possibly like many others was forced to payout for something that proved to be never required. Pure profit for the equipment sellers and a total loss to us. VOSA and the equipment people must have had a bloody good christmas on us fools back in the day. 

we got a dga 2500 and its been a damn good machine after mods.also got a dga 5000 last year and while we never needed to connect it we were told it was capable of it and the laptop im typing this on has no probs seeing it on wifi etc so i gotta assume its capable of it.what is the exact problem?extra software for connected equipment or just not capable?

i am looking at a new machine but i think i will wait a while just too see what these machines are like in the real world my tech says hard wire them not blue tool that is were you get the problems i have too replace mines in the next 5/6 years as i want retire and have to have the new machines if i want too sale the place for the right money i dont think there is any way round not putting the new stuff in

THIS is what annoys me! At a stroke the DVSA have effectively made my business unsaleable, or at the very least knocked a huge chunk off it's value. And for what real purpose?
I'm 71 this month and if/when we all have to upgrade equipment I'm just packing it in. And I must be far from the only one thinking that way!
