Hoje tenho alguns, 1900, 1841 x2, tudo em nome da Rede e bons costumes!
Então, vamos lá! Você irá precisar de um cabo Serial, da própria Cisco ou aqueles que toda T.I joga fora, porque nunca tem uso kkkk.
Já recuperei, Switchs e Roteadores com estes cabos e ainda hoje se faz muito necessário. Seguindo.
Abro o Roteador Cisco e retire a memoria Flash ou desconecte ela, e Ligue o equipamento ja com a serial em seu PC.
Utilizo aqui o bom e velho Putty.exe, segue link: https://the.earth.li/~sgtatham/putty/latest/w32/putty-0.73-installer.msi
De Open no Putty,exe, e siga os passos abaixo:
