Hey all,
I just got my 3550 delivered today and finished uploading the latest image.
I had a couple of complications with the install that might have generated this new issue. When I transferred the image via XModem, I changed the baud rate to 57600 for a quicker speed. Now that the image is installed and I can to the CLI, I found a troubling issue. (all dealing with a console connection)
When I boot into Rommon, I use a baud rate of 9600. When I load the IOS, I have to use 57600. The complication is that I have stated "set BAUD 9600" in rommon after "flash_init" and "load_helper". I have also tried "unset BAUD". After I set those parameters, I reboot and find that I need to use 57600 still. I have tried multiple variations of setting the baud rate back to its default. For instance, "set BAUD 9600" then "reset". "Set BAUD 9600" and unplugged the power cable. I tried not initializing the flash and changing it, but no luck.
I have copied out from the CLI. I start off in 9600 baud, and after the loader reaches a certain point, I get the weird text and have to change to 57600 baud to read the CLI. Example:

Is there a way to adjust the baud rate from the IOS CLI? I wouldn't care too much, but I have a terminal server connected to my devices and this makes it useless.

I found a resolution.
You can adjust the speed on the "line con [1]" using "speed [speed]". This seems like an artificial way to resolve the issue, but it works. GL to anyone else!
