Putty Ymodem File Transfer
I'm putting a new image on a switch and don't have access to Hyperterminal pay to use emulators. I'm using Putty and I'm not finding any Xmodem options with it.
I know the other emulator that is popular is TeraTerm but when I go to the site to download it hasn't been updated since 1999?? Any suggestions on free emulator that supports xmodem? Thx BbI just did this over the weekend also, and I was not able to figure out how to do it with putty either, I ended up getting out an OLD laptop that has XP on it to use HyperTerminal. My reason for saying this was that while doing that, I was wondering what I might do later when I dont have that laptop anymore, I was thinking I might use Virtual XP mode under Win7 next time, I have not done this yet but its just a thought. The last time I accidentally blew away the IOS on an old switch and had to use xmodem, I just used Hyperterminal with WinXP. Does Windows 7 not have Hyperterminal?
I've never seen it but was thinking about upgrading.Nope, Win7 does NOT have HyperTerminal, but you can install Microsoft Virtual Machine w/ Win XP Pro (free Download from MS) that does have it. There of course are some basic hardware requirements, but pretty much if you have any dual core processor, you will be able to setup a basic XP Pro Virtual Box easily.
I have it running on several machines with no problems, the lowest machine its on is a Pentium 4 Dual Core and it runs just fine. Hi, TeraTerm is my tool of choice. When sending files, sometimes the xmodem (File-Transfer-XModem-Send.) feature will not send, and in sending a new image to a 3550 found every error under the sun.!!! Eventually (2am) I downloaded the image again, changed the speed to 9600 and let it go. All good in the morning! Benefit of Teraterm is that it allows you just to browse to the image file so it can be on a USB or the local drive. On linux, I use minicom.

Worked for my 2950's but not for the 3550(?)! Minicom takes a bit more setup. I have two minicom profiles setup so when I change the BAUD rate, I can use a different profile without altering my usual Console connection settings. You could always just have it pull from a TFTP server as well. It's a lot quicker. Solarwinds has a good one.
You can install it on your computer and as long as the switch is connected to the lan and configured properly, it takes about 5 minutes to transfer an image.This x1000. Just setup your computer as a tftp server (I use tftpd32). Configure the ip/gateway/subnet on the switch/router and let the magic happen. I've always used SecureCRT. Just got used to it, so of course it's my terminal of choice. TechExams.Net is not sponsored by, endorsed by or affiliated with Cisco Systems, Inc.

Big File Transfer
Search Engine Optimization by 3.6.0.
I brought a new hardware (connected through USB as /dev/ttyUSB0). I need to transfer a binary os.bin file through serial.
The hardware has a inbuilt UART driver. I downloaded putty & couldn't see any file transfer method in the options. But I do see file transfer options in Teraterm, but many: kermit, X,Y & ZMODEM, Quick Van and B-Plus. Now, I don't know about any of the protocol mentioned above. I expect the new hardware to have only UART driver. (at a specified baud rate 115200 8N1 as mentioned in the manual) Now, how can I tranfer os.bin to HW?
& Which option should I choose in Teraterm if I use Teraterm? Using the Teraterm File - Send file. Command will send the contents of the file, but you still need something running on the remote machine to receive it (otherwise it just dumps the contents of the file to the command line or whatever other command processor the remote machine is running).
Although I'm sure there are better and more sophisticated ways to do this, I sent a text file by opening an editor on the remote machine (I used vi but ymmv) and then executing the Teraterm File - Send file. Command, so the contents of the file were dumped into the editor. The principle is the same for Kermit, Xmodem, etc., in that for any of these to work you need to be running the appropriate program on the receiver (e.g. Kermit) before initiating the send on Teraterm.
