           Summary: PCMCIA Card to RS232 don't work
           Product: Drivers
           Version: 2.5
     KernelVersion: 2.6.23
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: PCMCIA
        AssignedTo: linux-pcmcia at lists.infradead.org
        ReportedBy: johnrdoe63 at cregion.ru

Latest working kernel version:
Earliest failing kernel version:
Distribution: gentoo
Hardware Environment:
lspci - 04:06.0 CardBus bridge: Texas Instruments PCIxx12 Cardbus Controller

Software Environment:
module-init-tools 3.4

Problem Description:
I try serial the modem, by means of the program minicom. At start on the modem
bulb TR (terminal ready) lights up and hangs on a line of initialization. At
initialization the line is entered: AT S7=45 S0=0 L1 V1 X4 &c1 E1 Q0, in the
answer should be OK. Then ATZ, in answer OK. At use of the built in modem, all

Steps to reproduce:
1) run: minicom -o
2) choose: configuration and set serial device to the /dev/ttyS0
3) choose: init.

I modprob yenta_socket and insert PCMCIA Card:

ttyS3: detected caps 00000700 should be 00000100
0000:05:00.0: ttyS3 at I/O 0x4478 (irq = 18) is a 16C950/954

Why ttyS2,3 If interfaces only 2?
