As I recall, the Dell 310 has the serial ports built into the motherboard -- which means it's unlikely it has anything even remotely resembling an 8250, 16450, or 16550. More likely than not, it's got some sort of VLSI chip that has the UARTs, the "glue" chips, and everything else necessary for serial and parallel ports in it. You aren't going to be able to replace this with a 16550, because you'd be replacing your entire I/O subsystem, more or less. My advice would be to stick with what you have, if it works. If you start losing characters at high speeds, then your only choice will be to disable the ports on the motherboard and buy a separate I/O card with a 16550 on it. -- Marc Unangst | mju@mudos.ann-arbor.mi.us | "Bus error: passengers dumped" ...!umich!leebai!mudos!mju |
