Measurement
This item allows you to select the parameter RTM will use to end its measurement of a
response time. All response time measurements begin with the depression of a host attention
key. Choose one of four options:
• First Character Choosing: this parameter ends an RTM measurement when the first
character is displayed on the screen after a host attention key is pressed.
• Keyboard Unlocked Choosing: this parameter ends an RTM measurement when the
keyboard is reset for use after a host attention key is pressed.
• Change Direction/End Bracket (CD/EB): In SNA operations, choosing this parameter
ends an RTM measurement when a Change Direction (CD) or End Bracket (EB) is
received.
• Last Character Choosing: this parameter enables an RTM measurement from the pressing
of a host attention key to the receipt of the last character prior to the next pressing of a
host attention key. This measurement is not supported on DFT devices. If this option is
selected during configuration or by an RTM host request, RTM support is disabled for
the DFT.
The Change Direction/End Bracket option will function as Keyboard Unlocked if this profile
is assigned to a Non-SNA host on the 3270 Host Circuits panel.
RTM Boundaries
The four boundary items allow you to establish four boundary times for the RTM. The RTM
uses these boundaries to establish four categories for measurement of response time. Each
category is bounded by the times configured in this step. When a response time is measured,
its time is compared to the configured boundaries and a counter is incremented to indicate a
response time detected in the range of the matching category.
Rules for setting RTM boundaries are:
• Boundary values must be entered in ascending order
• Entries are made in minutes, seconds, and tenths of seconds. The maximum boundary
value is 27:18.3 (27 minutes, 18.3 seconds).
• If any boundary other than boundary four is configured as the maximum value, the
boundaries that follow must be configured to 00:00.0
• At least one boundary must be defined.
• If fewer than four boundaries are defined, the entries must begin with Boundary 1 and
continue without skipping through the last entry.
Host Support
This toggle field indicates if the RTM Support is with or without Host Support. The host must
have Netview or compatible network management software installed.
