Library /sys$common/syshlp/ncphelp.hlb SET, LINE, MICROCODE DUMP file-spec  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 Applies only to X.25 lines. Dumps the microcode of the specified
 KMS-11, KMS1P, or KMV1A device to the indicated file. By default, the
 output file takes the format:

 SYS$ERRORLOG:file-id.DMP

 The KMS/KMV Dump analyzer (PSIKDA) is the utility program used to
 process the dump file created by the MICROCODE DUMP parameter.  Refer

 PSIKDA.
