Using XMODEM

The XMODEM protocol built into the HP 48 doesn’t perform any

CRC checking, but it will work with a computer-based XMODEM

program that does. In this situation, you may have to wait a few
moments before the computer’s program gives up trying to perform
CRC checking and reverts to plain XMODEM.
