I have one router 1841 and switch 3750 and switch 2960 since last week until yesterday i test a scenario with these devices using unsuitable ips for real network and it was successful.
In MobaXterm, I am able to send Break, by Right-Click on console - Special Command - Break, but this is not similar to what is send in teraterm where we can hold Alt+B until we need to send Break. Send 'Ctl+C' command via the serial port. A Ctrl-C on a keyboard will break running code, but a keyboard is not connected using a serial port. A ctrl-C is a special keycode mapping. Before cocky brush it aside as a not working idea? Besides which, my opinion is that Express VIs Carthage must be destroyed deleted.
Today i decided to make it real and also having a connection to the internet in my scenario.
I don't unplug the Lan cables which were connected to these devices ports from last week and connecting the console cable to each devices in turn, i began to config.
At first i set the 3750 vtp mode to server and second set 2960 vtp mode to client. It takes 20 minutes and i was waiting for 2960 getting the vlan databases from 3570 and suddenly I found that the putty does not get inputs anymore from keyboard.
After that i tested other two devices and they were the same two. i in google and:
1) Num lock solution doesn't work.
2) Scroll lock doesn't work.
3) Changing the cable doesn't work.
4) I can't use pause/break to make them reset factory because it is the keyboard key and it doesn't work.
5) Any reset option from switch mode on the switch does not work i tried.
I am so confused because it seems don't have any control on these devices.
Any help would be appreciated.

I've had similar issues on some switches when Parity is enabled.Check your Serial settings in PuTTY.
Here's what I have set which also should be the default:
Here's what I have set which also should be the default:
Speed (baud): 9600Data bits: 8Stop bits: 1Parity: NoneFlow Control: XON/XOFF
According to the getting started guide flow control should be disabled.Have you tried changing the flow control setting to None? https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst3750/hardware/quick/guide/3750GSG3.html
