it seems odd to me that opening the ctl file would
reset some serial parameters.  wouldn't it be better
to leave them alone?

static int
dopen(Usbfs *fs, Fid *fid, int)
{
	ulong path;
	Serialport *p;

	path = fid->qid.path & ~fs->qid;
	p = fs->aux;
	switch(path){		/* BUG: unneeded? */
	case Qdata:
		dsprint(2, "serial, opened data\n");
		break;
	case Qctl:
		dsprint(2, "serial, opened ctl\n");
		if(p->isjtag)
			return 0;
>>		serialctl(p, "l8 i1");	/* default line parameters */
		break;
	}
	return 0;
}
