jumpers are on the modem card or in the external modem, you have to change com port and Irq settings with jumpers. And normaly have a choise of two different com settings

Not all modems support jumpers

I do realise this but Ill put it to you the Q i have is write down which pins on JP1 and JP2 would be shortened and at what positions in order to achieve the correct configuration/ and the second part goes on to ask wrtite down the displays I would expect to see once these changes have been made by running a diagnostic testing

You would have to have a particular modem or diagram to know what to look at. As they are\all different
