1.) Fix for modem unable to connect when ATH1 then ATD or ATH1 then ATA commands were issued. 2.) Fix for modem hanging up when switching from voice to data mode using AT+VNH=2. Previously, it wasn’t a complete hang up and the modem would be in a confused state. 3.) Fix for Analog Loopback mode. AT&Q6 and AT&T1 now work with no garbage characters. Previously, you would get CONNECT message and then garbage. 4.) Fix AT-TTE command, so parameters 5 and 6 display correctly. Previously, parameter 6 would overwrite 5 and parameter 6 would be unchanged. 5.) Modify DC offset voltage for ring detection to work better with Viking Line Simulator. 6.)
