Feature request:Wait

Apologies if there is already a way to do this but I can't find it.

I am trying to trigger a telnet or ssh script from Shortcuts and A-shell. Its to change router settings. I can trigger telnet and get it to connect. Where I struggle is the subsequent adding of data into the telnet. I can send the telnet command and then other commands from the same Shortcut entry but then they are entered immediatly. A-shell doesn't seem to recognise sleep or wait commands. Any chance of getting a sleep command added?

This is the terminal script that works (on osx) and I am trying to replicate in a-shell

#!/bin/bash
{
sleep 0.5
echo "username"
sleep 0.1
echo "password"
sleep 0.1
echo "config"
sleep 0.2
echo "int ge3"
sleep 0.2
echo "power inline never"
sleep 0.1
echo "exit"
} | telnet 192.168.1.240

Cheers all,
