i have make this change in Class2.c++ but i'm not sure if the change is
correct... :

--------------------------
Class2Modem::parseClass2Capabilities(const char* cap, Class2Params&
params, bool isDIS)

{ ....

// new codes
    char* c;
    if ( c=strrchr(cap,':') ) c++;
       else c=(char*)(cap);
// end of new codes

    if (useJP) {
	n = sscanf(c, notation, // orig: n = sscanf(cap, notation,
	    &params.vr, &params.br, &params.wd, &params.ln,
	    &params.df, &params.ec, &params.bf, &params.st, &params.jp);
    } else {
	n = sscanf(c, notation, // orig: n = sscanf(cap, notation,
	    &params.vr, &params.br, &params.wd, &params.ln,
	    &params.df, &params.ec, &params.bf, &params.st);
	params.jp = 0;
    }
 
// thats all
----------------------------

and the modem/hylafax work correct.

this might be a modem ( firmware?? ) error but i find no one similar
have anyone this seen anywhere ?
thanks in advance,
norbert
