Description Kazankov Alexander 2008-06-21 11:50:54 UTC

Latest working kernel version:
Earliest failing kernel version:
Distribution: gentoo
Hardware Environment:
lspci - 04:06.0 CardBus bridge: Texas Instruments PCIxx12 Cardbus Controller
PCMCIA Card - http://www.rovermate.com/site/accessories/home.nsf/descriptions/RMA19

Software Environment:
module-init-tools 3.4
pcmciautils-014
udev-115

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 works.

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:

lspci:
05:00.0 Serial controller: Oxford Semiconductor Ltd Unknown device 9505
05:00.1 Bridge: Oxford Semiconductor Ltd OX16PCI954 (Quad 16950 UART) function 0 (Disabled)

0000:05:00.0: ttyS3 at I/O 0x4478 (irq = 18) is a 16C950/954

Why ttyS2,3 If interfaces only 2?

Could you try the kernel 2.6.27?

Comment 2 Kazankov Alexander 2008-11-09 21:52:32 UTC

Same result.

Well, "lspci" seems to say "Quad UART" -- so I see no surprise that there are four ports being detected, even though only two ports are connected externally. Does a newer kernel work?
