Issues resolved in 4.4.7c Modem would not follow DTE rate for maximum connect rate. For example, if the DTE was set for 9600, the highest the modem should have connected was 9600. See current issues for further details. &I value in i4 screen would revert to default value instead of value programmed into memory when &Fn was issued. Display issue only. Modem would not respond to diagnostics query after install. Modem would send a few garbage characters after connecting in non-ARQ mode. Implemented a 30ms delay before displaying the connect message. Modem would turn off its 2100 answer tone when s27=8. The result would be a 300 baud connection from another modem. The modem now correctly keeps its answer tone on as the previous 5686E did. Modem would install as a serial mouse or fail detection. Modem would hang when certain non printable characters were sent to the modem before any AT command. If calling a modem with only MNP capabilities, the modem would incorrectly connect with no error control. Modem would not send v42 disconnect message upon hang up. Configuring S registers by bit addressing is not functional. Applies to all registers that have multiple bits. S27=16 does not enable v23 Fast Connect feature not enabled with s41=128 Modem cannot correctly display I screens at 7e1 or 7o1 Q2 function displays RING messages Modem fails to respond to commands when DTE is 1200 7E1 or 7O1 At 1200 7E1, modem will not respond if commands are in lower case (e.g. at&f1). At 1200 7O1, modem will not respond if commands are in upper case (e.g. AT&F1).
