[Coco] Smartwatch setting from Basic09

[Bill Pierce]

George, if you're using setclk, then you most likely have a B&B hard disk controller right? SetClk & GetClk are part of their package for the XT-RTC controller (maybe same for others?). I have one myself, though I don't use it anymore. I have to find some Seagate ST-225 drives for it (or others as those were the most popular) Mine had 2x 20 meggers. I use Drivewire now and it has a clock updated by you PC time once every minute or so. Dead on time.

 This morning early, I was thinking on this very thing. It wasn't setime I used, 
it was setclk. Danged memory. 
 I intend to do some testing today on this very problem and see exactly what I 
have done and what the results were. 
 Last year, I banged my head and my memory isn't all there. So I have to refresh 
it as much as I can. 
 I'm sure I was simply using the wrong syntax in a B09 program to use "setclk". 
I'll try this again to see if I can or can't get it to work, then I'll have an 
update to this list on my findings. I'm sure it was me and not the software.

time and needs adjusting ocassionally.

Before, I used "Settime" or "Setime"( can't remember right now) but, that was 
from the command line. Does the new OS9 clock module allow this or can I use the 
original clock. I don't really care about the year thing. If it says it's 1913, 
I'm good with that.

  Setime is an OS-9 command to adjust system time but will have no effect on a 
  real time clock (RTC). Your use of smartwatch is confusing as that is a 
  copyrighted name for a specific RTC but it seems you may be using it as a 
  generic name for all RTCs.

  To set an RTC, you must know the specifications of the unit as they require 
  different command sequences to both set and read the time. Except for the very 

  simple emulations of RTCs in some Coco emulators, the code sequence will be 
  complicated enough that an assembly program rather than Basic09 will be your 
  best bet.
  In addition to sending the correct sequence, you must be sure that the RTC is 
  "in memory". For that, you must know which I/O bytes are used and if OS-9 
  currently has those bytes available. That is not a trivial matter on a Coco3 
and 
  you likely may need to reset the GIME and MMU registers. Then there is the 
issue 
  of where the physical location of the RTC is and that may require checking 
each 
  MPI slot.

  I have written and sell code that supports the SmartWatch (r) for both Basic 
and 
  OS-9.
