Red Hat Bugzilla – Bug 57497
Using decompression with X/Y-modem has problems
Last modified: 2007-04-18 12:38:42 EDT
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.
Created attachment 41712 [details]
patch to strip extra ^Z characters at end of buffer
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).
