It seems to be exactly what happened in my case wth the Arion chess engine.
When you will have some time to solve that please let me know.

I downloaded and installed arasan 9.5 from
http://www.arasanchess.org/downld.html
I ran arasan.exe, and the gui worked.
I ran arasanx.exe, and the stdio interface worked (I was able to enter
commands like
e7e6 and e2e4, and get plausible responses).
In J, I defined:
spawnio=:3 :0
require'task'
cocurrent 'jtask'
'or ow'=.CreatePipe 1
'ir iw'=.CreatePipe 2
ph=.(ow,ir) CreateProcess y
if.1>ph do.
CloseHandle or,ow,ir,iw
assert.0
end.
CloseHandle ow,ir
iw,or
)
arasanx=:3 :0
spawnio (2!:5'APPDATA'),'\arasanx.exe'
)
rd=:ReadAll_jtask_
wr=:WriteAll_jtask_
Then, I tried:
arasanx''
548 424
rd 424
At this point, my J session "froze". I then went to the OS, and ended the
arasanx process. As soon as I did this, J returned the text of the first
line
from arasanx:
Arasan 9.5 Copyright 1994-2006 by Jon Dart
If I wanted to make this work, I'd have to figure out how to read and
write lines. (task.ijs does not include a ReadLine verb.)
I think I know how to make this work (actually, I have several ideas
I could try), but I don't have time to mess with this right now.
