Am trying to do password recovery for 2 VG224 but am unable to get to the ROM MON mode. I have connected a laptop with DB9 connector and trying with hyperterminal using Ctrl+Break sequence.
Password recovery is the same procedure as any other ISR. Send a break at boot, after the memoy count is finished.
Sounds like you may have a local terminal issue. Perhaps try an application like Putty or Teraterm to send the break sequence?
