Display history data in Compressed ASCII format by sending:
CHI <CR>

"REC_NUM","MONTH","DAY","YEAR","HOUR","MIN","SEC","MSEC",
"EVENT","LOCATION","CURR","FREQ","GROUP","SHOT","TARGETS","EVE_ID",
"yyyy"<CR>
xxxx,xxxx,xxxx,xxxx,xxxx,xxxx,xxxx,xxxx,"xxxx",xxxx,xxxx,xxxx,xxxx,xxxx,

(the last line is then repeated for each record)
If the history buffer is empty, the relay responds:
<STX>"No Data Available","0668"<CR><ETX>
where:
"xxxx" = the data values corresponding to the first line labels.
"yyyy" = the 4-byte hex ASCII representation of the checksum.
