i am cygwin guy:
i used to Poderosa, which support ssh/Serial Port/Telnet/cygwin
but i found Cmder /CmdEmu better than Poderosa/console2/consoleZ/powercmd now.
Poderosa/console2/consoleZ — can’t find
powercmd — can find ,but can’t display color character (like red color error msg)

MobaXterm — it is not pure command terminal , need money. but i think mMremoteNG (free) better than this one.
