Without knowing details, I'd assume that it's a different interpretation
of the xmodem "standard".

Later versions of xmodems require that the final packet is ACKed twice,
to cope for potentially garbled bytes that are mistaken for an EOT ("end
of transmission") packet.  Earlier versions send only one ACK, and then
the receiver exits.

If that theory is true :-) your xmodem upload will actually work, even
if minicom complains about it.
