    Alternatively Chris, if you can wait a couple of months I'm going to be writing a small app that communicates with a virtual Idratek device and the serial port and transfers data between the two. I'm using it for some RGB controllers but it wouldn't be too difficult to change the strings within it to have the functionality you need.

    Am very busy atm though with both my house and work unfortunately.

    Geps - that would be brilliant, ace ...

    we need to send ASCII strings to & fro at 1200 baud (full duplex, GND TX RX, one start & one stop bit, eight data bits, no parity) - in case of interest, details are here :

    Hmm, doesn't look too horrendous.

    I'll contact you nearer the time. Prod me if you don't hear anything in case I've forgotten.

    Cheers,

    Why not convert to RS422 and sent it over CAT5. ?

    You may find that the serial ports on your PC already have that option built in so you would only need the RS422 line drivers at the distant end.

    RS422 - yep, might well have to do that, to increase the range, co-location being tricky to achieve in our case ...

    'have a feeling Geps' prospective code will be the start of something big, because RS232 comm's are quite widely used, in AV devices & a host of others, and if it can be readily adapted from his application to mine, then ... magic !

    being able to send & receive would be key ... plus maybe extensibility in the virtual Idratek device ...

    Does Idratek already have RS422 support then?

    I assumed we'd have to convert (to/from RS422, or whatever) at each end of the Cat-5e ...

    Ah ok - that makes sense.
