To do this, go to Control Panel->System->Device Manager->Modems and select the serial cable. Proceed to the 'modem' option and select a maximum speed of 115200 or whatever your linux computer is set to. Now, it is important that you reboot at this stage, or it WILL NOT WORK (at least with Microsoft windows 95 version A), I am not sure about others.
