You are right, currently, the CaWave does not support the monitoring of the
waveform record.
However, in the aps_wish ( a TK/TCL version of channel access) it supports the
monitoring of waveform record in HEX/BINARY/DECIMAL. It is available as an
extensions tool. The usage of monitor of waveform can be found in the simple
document
/usr/local/epics/extensions/doc/aps_wish.doc.
If the document does not mention the monitoring of waveform record, you need get
the new release epics/extensions.
An example of monitoring an waveform record 'chademowf2' in aps_wish is given below:
aps_wish
ezcasetmonitor chademowf2
set WF(chademowf2)
The above 'set WF' command will print the current values of the wave from record.
