I want to change the ser.cfg. Such as I want to define a new variable, and assign a string, etc But I don’t know which language the ser.cfg use. Is there any document to introduce the expression and language of ser.cfg? THANKS 王振中 wangzz 艾诺通信系统（苏州）有限责任公司 苏州工业园区国际科技园一期203A wangzz(a)avonaco.com ============================================
