Even after Sftp is turned off, the HuaWei switch cannot be connected, but both CRT and PuTTY do not have this problem

Sorry for the late reply. Recently I have been focusing on developing WindTerm_2.4.0_Prerelease_2.

Thank you. WindTerm does have problems connecting to some devices, such as routers and switches, and there have been several issues about this. I will try to fix these bugs in version 2.5.0 or 2.6.0. It's a bit slow to process since I don't have a device to debug quickly. Please stay tuned, thank you.

2.5.0 still have this error Cannot login to Huawei devices

这么晚才回复很抱歉。最近我一直专注于开发WindTerm_2.4.0_Prerelease_2。

谢谢。WindTerm 确实在连接某些设备（例如路由器和交换机）时遇到问题，并且已经出现了几个与此相关的问题。我会尝试修复版本2.5.0或2.6.0. 由于我没有可以快速调试的设备，因此处理速度有点慢。请大家继续关注，谢谢。

Dear software author, if you do not have a physical server for testing, you can use Ensp and Cisco Packet Tracer to simulate Huawei and Cisco switches
