Appendix E Communications Status Codes
Communications Status Codes
When the Program Loader and Memory Transfer utilities complete their functions, they
return communication status codes in the form of a four hexadecimal number. A status code
of 0000 indicates success; any other code indicates failure. Table E-1 describes the conditions
associated with the status codes.
