使用ROBOT SSH库传递多个命令选项

Question

I am new to RF and trying to autmoate user account on test machine.
Once the main command nmc@myhost:/$ "create appliance user john" is executed
it will ask for multiple inputs one by one with enter key press in each level. 
I tried with write and read keywords of SSH as below and not able to get success.

手动测试执行输出。     ============================     nmc @ myhost：/ $创建设备用户john     主文件夹：JOHN / Test     说明：测试     默认组：员工     密码：xxxxxxxxxxxxx     确认密码：xxxxxxxxxxxxx     NMC @为myhost：/ $
