Hello,
the following installed rtf handler doesn't work on read ops from user space.
On write ops the handler is called. Refering to the man page, both should work.
My fault or a bug in rtf_fifo of 2.2.18-rtl3-final?
Regards
Olaf

rtf_put(number(), &sz, sizeof(sz));
rtf_put(number(), (void*)msg, sz);
