Block Mode Operation
6530 Programmer’s Guide 3-65
Five buckets will be configured by setting 4 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 3-92 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:
p1: Response Interval Start/Stop Events
1 = Any function key press / keyboard unlock command receipt
2 = Any function key press / any host data receipt
p2: Number of Buckets
1 to 10
A value of 1 is valid. It is not followed by a bucket partition
because it defines a bucket with boundaries from 0 to infinity,
which counts every response.
pn: Bucket Partition (centisec)
pn occurs number of buckets - 1 times. The ASCII numeric
string specifying each bucket partition may not exceed 5 digits
and may not exceed a value of 65535.
