requested configuration (rg is the last
character of the message for this
error; this error message would only
be generated as a response to a
System/360 control request and is
equivalent to the X'01' catalog num­
ber-invalid panel request).
X'F1'— The 2790 adapter error detected
(catalog number X'95' was also set
on the 2715 panel).
X'F2'— A segment had to be bypassed
(catalog number X'96' was also set
on the 2715 panel) because of an
error condition.
X'F3'— The 2790 transmission system
would not sync (catalog number
X'97' was also set on the 2715 panel).

X'F0F1'— Segment was already bypassed,
or was requested to be bypassed.
X'F0F2'-Segment had to be bypassed
because nothing was received from

Invalid Responses. Standard response used for checking
Bypass/Restore requests for valid segments.

Panel Responses. Any valid panel request that affects the
status of the 2790 system (i.e., C3, C4, or C l) automat­
ically causes a response message to be sent to System/360.

b. Negative— The following catalog numbers correspond
