baud
Sets the baud rate and communication settings for a UART.
Syntax
baud <index> <baudrate>
Parameters
<index> 0 through the total number of UARTS minus one
<baudrate> baud rate.
Operation
This command is used to change the speed for a UART in the system. This command works for all UARTs
visible to EFI/POSSE. If the UART is part of processor dependent hardware (PDH) space and is initialized by
the core firmware, this command communicates the settings to core firmware so the UART can be initialized
with the new settings on the next boot. System default is 9600 baud.
Other Communication parameters are listed in Table 4-2.
boottest
Interacts with the speedy boot variable allowing it to be set appropriately.
