Class 2.1
+FPS:
Syntax:
+FPS:<ppr>,<lc>,<blc>,<cblc>,<lbc>
The +FPS:<ppr> response is generated by the modem at the end of Phase C data
reception in execution of a +FDR command.
reception in execution of a +FDR command.
The <ppr> response is generated by the modem; it depends on the modem for T.4 or
T.6 error checking capabilities, controlled by the +FCQ parameter. See Table 3.0 for
<ppr> values.
T.6 error checking capabilities, controlled by the +FCQ parameter. See Table 3.0 for
<ppr> values.
The receiving modem may count lines and bad lines and report them. Values are:
<lc> line
count
<blc> bad
line
count
<cblc> consecutive bad line count
<lbc> lost byte count due to modem buffer overflow
The line counts are qualified by the modem’s copy checking capabilities, controlled
by the +FCQ parameter. If the modem is not configured to count lines, or if line
counts are irrelevant (e.g. in Binary File Transfer mode, Recommendation T.434) the
modem sets the line counts to 0.

counts are irrelevant (e.g. in Binary File Transfer mode, Recommendation T.434) the

A receiving host may inspect <ppr> and write a modified value into the +FPS
parameter. The modem will hold the corresponding post page response message
until released by a +FDR command from the host.
