Yes, that's right. buysbox/msh has some problems when it comes to

The question is what is feeding the pipe ?
You should be able to do a simple program that sends the characters to
the pipe using the appropriate timing and pipe same to

Hi Tom,
Thanks for the help. I tried enabling msh (I think it was already

At least on my Busybox-based system, telnet cannot be used with input
from a pipe.
If you do that, it just exits with status 1 (error status).

Is there a way around this?
Try building netcat instead (the command is usually nc).
It's more appropriate for this job, and should build easily.

In the meantime, I collected some more information while trying this with
