The information Paul showed indicated W0JW had turned off Mic-E translation (good because it was turned on in the screenshots provided earlier) but the 0x1c character was still being stripped.  This is usually a case of either the TNC being in command mode not KISS mode, or the software handling the packet data as a string, not bytes.

Hope this helps W0JW isolate the issue.  If it is a software issue, I hope W0JW contacts the author with this information.
