i know i'm boring with this:

but

does the same ircd on different servers has same umodes and cmodes OR that depends on services ?

User modes are usually ircd specific, but they
can also load modules that may add user modes.

Easiest thing to do is to check raw 004 & 005
when you connect to the server for exact user
& channel modes available.

but in most cases it is set up by ircd huh?

affirmative

thanx much

iowghraAsORVSxNCWqBzvdHtGp lvhopsmntikrRcaqOALQbSeKVfMGCuzN

those are both usermodes and channel modes supported, in unreal i believe u can obtain this list by using /helpop chmodes or umodes and u can get that full list hope that helps u out.

yeah, thanks.
