		Hi reader !

I try to get some data values over a link from a T225 tranputer (64k SRAM).
As I read in the inmos transputer databook it is possible to go
3 ways handling a (non-booted) transputer:

poke - byte 00 as the first, then 2 bytes address and 2 bytes data
peek - byte 01 as the first, then 2 bytes address (get data the same link)
boot - anything >=02 (number of bytes bootcode)

When I do the 'poke' everything seems to be okay but a 'peek'
doesnt work for some unknown reason. Even if I write a
0x0101010101... serie the T225 doesnt read this value in so the other
processor (which writes this value) blocks. That serie means to read a
value from location 0x0101 and write it back over the same link.

So what happened? Is the above way the right one? Do I forget anything?
Does the T225 work in this way (like the T222)?

Any help welcome,
			Bernd.
