Here are the recommended emulator settings Configure the terminal emulation software as follows: a Select the appropriate serial port (serial port 1 or serial port 2) to connect to the console. b Set the data rate to 9600 baud. c Set the data format to 8 data bits, 1 stop bit, and no parity. d Set the flow control to none. e Set the terminal emulation mode to VT100. f Select Terminal keys for Function, Arrow, and Ctrl keys. Make sure that the setting is for Terminal keys Found on page 10, here. support.dell.com/.../gsg_62.pdf  I would double check these settings. If still having an issue, then try a different emulator. Keep us updated, thanks.
I'm reviewing the PDF for upgrading the firmware on our Dell 6248 from 2.0.0.12 to 3.3.4.1, and the procedure to update the boot code appears to require serial access to the switch. Step #2 states "Power up the management unit, stopping at the Boot Menu." I'm able to get a serial connection from a Ubuntu laptop using cutecom, but not all the commands appear to be working properly, and it doesn't appear to be a live console. How am I supposed to get to the Boot Menu? Do I need to use a better terminal emulator software?
