How does Windows 3.x/95 know there's a serial modem connected to the COM port? Does it do something special with RTS/DTR? Does it expect certain behaviour on CTS/DSR with those two other lines(RTS/DTR)? What about the Hayes/Microsoft PNP specification? Is that used with Internet Explorer 5 on WFW 3.11? Or perhaps a combination of all of those?
The install new modem wizard won't properly seem to detect the modem(CTS forced to RTS, DSR is always 1, like in Dosbox)? Besides that, the modem algorighm from the Hayes modem specification(the two delays(T1/T2)-based timing with DTR/RTS) is also implemented.
