User Zone / BMC console com2 on Talos II
« on: June 07, 2023, 02:36:47 pm »
Hello, I've got one of these TTL/USB serial adapters that are suggested in the wiki and am
able to get output at 115200bps 8n1 which appears to boot up the BMC.  Unfortunately I don't seem
to be able to interrupt the boot process by "pressing any key" nor able to login.  I've tried setting
and unsetting software flow control to see if I can get any input.

The cable is pretty simple, TXD/RXD and GND.  I am not using the power lead (it shouldn't be necessary).

Is there something else I should be doing?
