Currently, in Telnet devices, the “backspace” key does not work in the conventional way as expected.
The key combination Ctrl + H is used as an alternative to the Backspace key. By pressing this combination, the character before the cursor will be deleted, functioning similarly to the Backspace button on other devices.
The “delete” key is usually used to delete the character to the right of the cursor, and this behavior is expected in Huawei Telnet devices.
