iPXE already uses ANSI escape sequences internally for all console I/O, 
with an internal translation layer to drive the BIOS INT 10 and other 
non-ANSI consoles.

Are you using:

  (a) iPXE's own serial console support (CONSOLE_SERIAL in 
config/console.h),
  (b) some kind of serial console emulation provided by your BIOS, or
  (c) both

Option (a) should work.  Option (b) may work if your BIOS is good 
enough.  Option (c) is not going to work since both iPXE and the BIOS 
will be attempting to drive the serial port simultaneously.
