The solution is:
in /usr/lib/X11/xdm/Xresources, put the line:
dxlogin*XmText.blinkRate: 0
On the other hand, if you absolutely need to prove that your network
is overloaded, just put a 1 in place of the 0. The result is great :))

Here they are:
o to put your own designed (with bitmap for example) in place of
the fantastic Digital one, put in the same file:
dxlogin.bitmapFile: /usr/var/X11/xdm/my-logo.bmp
dxlogin.bitmapMaskFile: /usr/var/X11/xdm/my-logo-mask.bm
o to keep the great AXP logo in the bottom left corner for a later
advertising use, put still in the same file:
dxlogin.ShowAxpLogo: False
