Description Jesper Skov 2001-12-14 10:33:24 UTC
For some reason, the X/Y-modem protocol handling is messed up on the last
packet when using the decompression feature (-d), and minicom will hang
instead of closing the upload window.

Pressing ESC will get back the RedBoot prompt (possibly with a RedBoot
error/warning), but the data appears to have decompressed fine. This can be
verified using the 'cksum' command if critical.

Comment 2 George Thomas 2002-01-03 21:21:13 UTC
X-modem pads the final data record with ^Z characters.  The attached
patch strips them (if it finds at least 3 consecutive ones at the end).
