Access RomMon using USB connection

[joewalvoxbright]

                   I have a 1921 router.  Using usb cable I can connect to the console but cannot get the router into rommon mode.  I saw a post for a 1941 router where you can remove the flash to get it into rommon mode, but the 1921 flash cannot be removed.  I am using Mac terminal and screen command but am not able to send break signal.  would love to know if its possilble.

but the 1921 flash cannot be removed.

I think you can.  The CF is "hidden" behind a dust cover.  The slots are located at the BACK of the unit, to the left.  The back is where the ports and EHWIC slots are.

According to this link, the flash on a 1921 is on a daughter-board:

Had a close look.  Yes.  1921 flash is internal.
