I have a Latitude CPx500, 2.2r2, and a XIRCOM RBEM56G-100. I
had to turn on SHARE_IRQ to get the XIRCOM card working. From
/usr/src/linux/.config:
#
# Character devices
#
CONFIG_VT=y
CONFIG_VT_CONSOLE=y
CONFIG_SERIAL=y
# CONFIG_SERIAL_CONSOLE is not set
CONFIG_SERIAL_EXTENDED=y
# CONFIG_SERIAL_MANY_PORTS is not set
CONFIG_SERIAL_SHARE_IRQ=y
# CONFIG_SERIAL_DETECT_IRQ is not set
# CONFIG_SERIAL_MULTIPORT is not set
# CONFIG_HUB6 is not set
# CONFIG_SERIAL_NONSTANDARD is not set
CONFIG_UNIX98_PTYS=y
CONFIG_UNIX98_PTY_COUNT=256
CONFIG_PRINTER=m
CONFIG_PRINTER_READBACK=y
CONFIG_MOUSE=y
I also have to force the ethernet card into promiscuous mode to get it
working.
Before pcmcia card:
$ cat /proc/tty/driver/serial
serinfo:1.0 driver:4.27
0: uart:16550A port:3F8 irq:4 baud:9600 tx:0 rx:0
1: uart:unknown port:2F8 irq:3
2: uart:unknown port:3E8 irq:4
3: uart:unknown port:2E8 irq:3
After inserting card:
$ cat /proc/tty/driver/serial
serinfo:1.0 driver:4.27
0: uart:16550A port:3F8 irq:4 baud:9600 tx:0 rx:0
1: uart:16550A port:180 irq:11 baud:9600 tx:0 rx:0 CTS|DSR
2: uart:unknown port:3E8 irq:4
3: uart:unknown port:2E8 irq:3
