Panal's Modems actually calls the ATIx commands to get "More Info":
1. The port driver EscapeFunction() must support the GETCOMBASEIRQ option.
"More Info" fell down when the driver answered with IE_EXITINVALID. The

2. The virtual modem (port driver) must support following AT commands and
answer OK on the string: "ATE0Q0V1". The last commands are not set up in the

"at+fclass=?".
