6530 Programmer’s Guide
For example, specifying one partition at 100 centiseconds causes two
buckets to be created - one that counts the occurrence of response
intervals in the range of 0 to 100 centiseconds and a second bucket that
counts the occurrence of response intervals greater than 100
centiseconds.
RTM recording of response intervals is enabled on entry to block mode
and also each time the RTM Controls are reset. The RTM Controls for
terminals include definition of the response interval start/stop events, the
number of buckets, and the bucket boundaries (specified as partitions).
The default RTM control settings are:
RTM response interval start/stop events are any function key press
(start) and the receipt of the keyboard unlock command (stop).
The number of buckets is five.
Five buckets are configured by setting four bucket partitions at 200
csec, 400 csec, 1000 csec, 2000 csec, which results in the following
buckets:
Bucket: B1 B2 B3 B4 B5
Bucket boundaries: 0....2s....4s....10s....20s....infinity
The 6530 also supports RTM Definite Response. Definite Response
enables the host to elicit an expected 6530 response and measure the time
between the request and the response. The facility for this is the Simulate
Function Key (Esc d) escape sequence. See “Simulate Function Key (Esc
d)” on page 2-49 for escape sequence format information.
RTM Control (Esc - i)
The Esc - i sequence configures the Response Time Measurement
Controls.
The format of the escape sequence is:
Esc - parameters i
where:
- = minus sign (2DH)
i = lowercase i (69H)
parameters = ASCII numeric character strings, in the format
