Sorry about the delay...I'm afraid its 100ma, apparently there is
a R/C network across the relay, I go a reading of 196 ohms
(close enough to 200 ohms to call it that). This may be a
'fast acting' relay of higher ohmage, but the circuit might be
designed for a worst case of character by character control.

I'm afraid it's back to the drawing board.....
