hi. After recompiling, u must have compiled the serial driver built in and that may put your serial ports in diferent devices ( i mean /dev/ttySx ) Another thing is that you may have not compiled the serial driver at all ( not even as a modules); and when you try to use some hardware that is not detected ( because the driver is not in use) then you cant. But I suppose the problem is the first I mentioned
try to see what hardware is identified with cat /proc/ioports then man setserial etc On Wed, 26 Dec 2001, Saqib Shaikh wrote: > Hi Listers, > > I recently installed Debian 2.2R4 on my Dell Inspiron 3800 laptop which has > a Pion Gold Card PCMCIA modem.
