3274Model lC, or 3216, all specified as a 3211) on a leased BSC line,
or a standalone 3215 on either a switched or leasedBSC line. One CLUSTER macro must be specified for each 3271, 3214 Model lC, 3215, and
3276.
Note: EachCLUSTER macro must immediately precede the TERMINAL macros defining the devices attached at each remote 3210 station. The groups
ofCLUSTER and TERMINAL macros must precede all other macros in the DMKRIO file.

are the general polling characters that represent the general
polling technique to be used for this station.When general
polling is used, the first device that the control unit determines
is ready to send data over the line is allowed to do so. The
characters, cudv, are theQ-digit hexadecimal general polling
characters assigned to the control unit of the station. The
hexadecimal equivalent of the EBCDIC transmission code is in the
form cudv, where:
