Twinax Error Log

The 5250 ALLY makes a log of any twinax hardware errors it encounters
on the physical twinax line. Most errors encountered are parity errors
caused by faulty cabling or termination. This feature is useful for
diagnosing the cause of twinax errors. The twinax error log can be printed
using Mode 9-8.
SCS Dump and Hex Dump Samples
In order to illustrate the difference between the SCS Dump and the Hex
Dump modes, the following SCSGEN file was sent to the 5250 ALLY
three different times, once with the unit in Hex Dump mode, once in SCS
Dump mode, and finally in IBM emulation mode:
