Any attempt to use the modem via ppp or cu hangs the machine. The hang occurs at the point where you can start entering AT commands. The lines from dmesg associated with the serial ports are shown below... sio0: configured irq 4 not in bitmap of probed irqs 0 sio0 at 0x3f8-0x3ff irq 4 flags 0x10 on isa sio0: type 8250 sio1 at 0x2f8-0x2ff irq 3 on isa sio1: type 16550A Here are my questions... The kernel is reporting sio0 as a type 8250 rather than 16550A. I know FreeBSD works w/ 16550A UARTs but I don't know about 8250. Could this be the problem? Would the problem be solved by going w/ an external modem?
