It's been a long time since I've ever had to edit AT commands on modems. In my pppscript file, I have an AT command line. But when I go to edit it, I get either script failures or it doesn't do what I need it to. How do I modify the command line when dealing with a couple of different AT commands? Such as AT&, AT*, etc. Currently I have AT&FH0 in my command line, but need to add some other variables. Do I add them all in one string or can or should I do them in multiple lines?
