Not impossible to solve, but it may not be soon. If you could, please add a jira ticket for it https://jira.fd.io in the VPP project and assign it to me. Thanks, Chris. [1] Sending backspace to the terminal doesn’t do what you would expect on the left edge. This also impacts when you cursor-up/down through the CLI history if those lines are longer than the terminal width. From: vpp-dev@lists.fd.io <vpp-dev@lists.fd.io> On Behalf Of ???

How can this problem be solved? Example： first: VPP# aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaa then input 'backspace' , can only be deleted last seven 'a' VPP# aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
