When using Cisco devices, we need to send the break key command in order to get them to boot into ROMMON mode. Unfortunately, none of the alternate methods appear to work. We've tried pressing escape twice, tried the normal shift-control-6, and so on. If you could add the "Send Break" menu option from the RDP plugin into the Terminal plugin, that would fix our issue and we would be forever grateful. We have to revert back to SecureCRT to get into Cisco devices through serial console ROMMON and it makes us sad.
