In Cisco routers, xmodem protocol is usually used for disaster recovery, t
o
load an IOS using the console port. In the rom mon mode, you type xmodem <file
name> and send the IOS file via Hyperterminal (or other terminal) using Xmodem
protocol. This procedure is slower than TFTP, because you are using console
speed, not LAN speed. You can increase the Xmodem tranfer, increasing the
console baud rate, but in this case, you can config the speed up to 115200 if
you are directly connected.... I´ve never loaded an IOS via modem connection to
the console port, but if you think in this solution, you can set the console
baud rate for the convenient speed, and try to load it.
Best regards..

Or is it a must that the router must be connected to LAN(with TFTP somewhere in
