- Detect CTS at startup to ensure it is asserted. If not, disable hardware flow control to avoid stalling the console at boot. Only for UART driver because this is the only place it is currently relevant.

|
; THE COMPLETE SET OF DEFAULT CONFIGURATION SETTINGS FOR THIS PLATFORM ARE FOUND IN THE
|
|
; CFG_<PLT>.ASM INCLUDED FILE WHICH IS FOUND IN THE PARENT DIRECTORY. THIS FILE CONTAINS
|
|
; COMMON CONFIGURATION SETTINGS THAT OVERRIDE THE DEFAULTS. IT IS INTENDED THAT YOU MAKE
|
|
; YOUR CUSTOMIZATIONS IN THIS FILE AND JUST INHERIT ALL OTHER SETTINGS FROM THE DEFAULTS.
|
|
; EVEN BETTER, YOU CAN MAKE A COPY OF THIS FILE WITH A NAME LIKE <PLT>_XXX.ASM AND SPECIFY
|
|
; YOUR FILE IN THE BUILD PROCESS.
|
|
;
|
|
; THE SETTINGS BELOW ARE THE SETTINGS THAT ARE MOST COMMONLY MODIFIED FOR THIS PLATFORM.
|
|
; MANY OF THEM ARE EQUAL TO THE SETTINGS IN THE INCLUDED FILE, SO THEY DON'T REALLY DO
|
|
; ANYTHING AS IS. THEY ARE LISTED HERE TO MAKE IT EASY FOR YOU TO ADJUST THE MOST COMMON
|
|
; SETTINGS.
|
|
;
|
|
; N.B., SINCE THE SETTINGS BELOW ARE REDEFINING VALUES ALREADY SET IN THE INCLUDED FILE,
|
|
; TASM INSISTS THAT YOU USE THE .SET OPERATOR AND NOT THE .EQU OPERATOR BELOW. ATTEMPTING
|
|
; TO REDEFINE A VALUE WITH .EQU BELOW WILL CAUSE TASM ERRORS!
|
|
;
|
|
; PLEASE REFER TO THE CUSTOM BUILD INSTRUCTIONS (README.TXT) IN THE SOURCE DIRECTORY (TWO
|
|
; DIRECTORIES ABOVE THIS ONE).
