Talking to a GPS module
OK chaps, I realise this is not audio so I won't be offended if the Mods chuck it in the bin.
I have a SSF2929P gps module which I wish to enable the ZDA string.
If I apply power to the module it happily spits out data, finds
sattelites etc and displays results on my terminal, but nothing I send to the module
will stop the flow of data and put it into a mode to accept the
commands.
I'm beginning to think comms with this thing is half duplex, not full
duplex.
If this is the case, how do I reverse the flow and make it listen ?
(Yes I do have Rx and Tx connected)
(Yes I have RTFM but TFM is remarkably silent on this issue)
Cheers
