A VT102 is a nonexpandable terminal equivalent to a VT100 with Advanced Video Option and Printer Port. In addition it supports half-duplex communication, asymmetric full-duplex (half duplex with secondary channel), and modem control, which the VT100 does not. The VT102 is a slower terminal than the VT100, hence the infamous "disable autorepeat" kludge in EDT. From a software standpoint, a VT102 is a VT100 with insert/delete line/character capability (considering that AVO is a "non- optional option" for VT100s, but most do not have Printer Ports, and DEC in their infinite wisdom tied insert/delete to having a printer port installed; note that the only real loss is the character functions, as the base VT100 supports scrolling regions.) -=EPS=-
