Please note that the slave immediately exits after sending the "5", thus implicitly closing the pty slave. Maybe this is the reason why the "5" is lost. A "sleep(1)" should help here.

Regarding echoing: setting the slave to raw with "$slave->set_raw()" should turn off echoing. This could also help with the lost "5".

Hope this helps,

Roland

PS: yes, ptys are VERY much black magic... :-)
