If you need more than 16384 characters then you just need to set the environment variable EPICS_CA_MAX_ARRAY_BYTES to a larger number on both the IOC process and the channel access client process.

export EPICS_CA_MAX_ARRAY_BYTES=1000000

will let you have 1 million characters.

    field(DESC, "testWaveRecord")
    field(NELM, 16384)
    field(FTVL, CHAR)
  }

use
caput -S   to write
