the preamble
is reported as a 0 <signal> value.
<1st message> The contents of valid V.8 bis message(s), if detected, are reported using
hexadecimal octet coded string(s) (A.4.1). Flag detection and consumption, flag
transparency 0-bit deletion and FCS
checking are performed by the modem. The modem does not report invalid messages
(e.g., bad
FCS). If two consecutive messages are detected but the first is invalid, the modem
indicates this
with no characters between the first and second comma (e.g., +A8R:<signal>,,<2nd
message>).
<2nd message See <1st message>.
Example
+A8R:0,XX,YY For a V.8 bis message detected without a preceding V.8 bis signal.
+A8R:0,XX,YY For a V.8 bis message detected with a preceding V.8 bis signal.
