I have an external device (running a small Linux-based OS) that I need to log in to via the Windows 7 command line. The device is connected to COM1 with a USB-to-serial cable. How do I do this without HyperTerminal (which doesn't come w/7)? I know how I'd connect to a remote IP address or similar location via ssh, but I'm not very familiar with Windows & am having a hard time finding info on how to replicate this particular function of HyperTerminal ...

All three suggestions (PuTTy, KiTTy, Tera Term) just returned gibberish, suggesting to me that maybe there's something wrong with the device, my cable, or I just need to read up on how serial ports work some more, I don't know (turned out to be a weird connection speed issue). But it's good to know there are alternatives to Hyperterminal (I really wanted Tera Term to work, too - the vintage 1999 brilliant turquoise website and Y2K disclaimer were fun).

Current versions of PuTTY can connect using a serial port.


The PuTTY fork KiTTy supports serial comms too and has some nice features that PuTTY lacks.

  • Thanks, I didn't know about this fork - looks like it'll work for an unrelated issue I had, too!

Tera Term is a good alternative to HyperTerminal - it's old but works fine on W7 - in fact, I was using it this afternoon on W7 (64-bit) to test an old modem on COM1.

    That website is absolutely incredible.
