Fix for modem unable to connect when ATH1 then ATD or ATH1 then ATA commands were 
issued. 
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. 
Fix for Analog Loopback mode. AT&Q6 and AT&T1 now work with no garbage characters. 
Previously you would get CONNECT message then garbage. 
Fix AT-TTE command, so parameters 5 and 6 display correctly. Previously, parameter 6 would 
overwrite 5 and parameter 6 would be unchanged. 
Modify DC offset voltage for ring detection to work better with Viking Line Simulator. 
Modify DTMF detection to display DTMF’s for valid digit presses. Previously, it would be just 1 
digit no matter the length of press.
