Your problem is spooky, I just had the exact same problem with a 1924 the other day. Same symptoms, same inability to use XMODEM to upgrade the flash. I discovered that not all null modem cables are made the same, strangely enough. Do a search on CCO and you will find a variety of pinouts. I finally found a null modem cable with the same pinout that is specified in the 1900 documentation for release 5.x:
