<LI>Defaulted subparameters in <TT>AT+FDIS</TT>
and <TT>AT+FDCC</TT> commands are wrongly treated as zero
<LI><TT>AT+FDIS</TT>
commands to set session parameters after establishing a
connection with a remote machine are accepted but ignored; this
makes it impossible to select/change data format (1D vs 2D encoding)
and vertical resolution (98lpi vs 196lpi); to workaround the problem
use the <B>Class2DDISCmd</B> configuration parameter
<LI>RTC appended by the modem on page transmit appears to be
invalid; the host should append a proper RTC
<LI>EOM followed by a T2 timeout is handled incorrectly; the modem
restarts Phase B of the protocol but then goes into an
indeterminate state
<LI>Page data reception is triggered by DC2, not DC1
<LI>Fax receive is locked at 19200 and only software flow control
appears to be supported
<LI>It is not possible to disable software flow control during
page data transmit
<LI>HDLC frame tracing (<TT>AT+FBUG=1</TT>) is not supported
