At startup, pcmcia-cs symlinks /dev/modem to invalid device

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040120 Description of problem: At system start-up the pcmcia-cs package correctly detects that I have a modem in a PCMCIA slot. It then creates a "/dev/modem" symlink, linked to the serial port /dev/cua6. That's bad because this devnode does not exist. Thus /dev/modem is a dangling (and useless) symlink. Manually removing the symlink and doing a "ln -s /dev/ttyS6 /dev/modem" fixes the situation and allows me to access the device via /dev/modem. Version-Release number of selected component (if applicable): 3.2.7-1.5 How reproducible: Always Steps to Reproduce: 1. Start pcmcia-cs daemon (as part of system startup) 2. The daemon correctly detects that a modem card is in the machine. 3. Actual Results: Bad /dev/modem symlink created, linked to missing /dev/cua6 devnode. Expected Results: Symlink /dev/modem should be linked to devnode /dev/ttyS6. Additional info: The pcmcia-cs daemon is aware of the actual serial port: # cat /var/lib/pcmcia/stab Socket 0: Serial or Modem 0 serial serial_cs 0 ttyS6 4 70 See file /etc/pcmcia/serial.opts for the setting of the LINK variable. I'm reporting this as Normal (rather than Low) in severity for the benefit of newbies who only know that the PCMCIA modem in their notebook doesn't work.
Normally doing the symlink will remove it and so on. The proper fix is to edit /etc/pcmcia/serial at line 46/110: The line is: if match `uname -r` "2.[2345].*"; then It should be if match `uname -r` "2.[23456].*"; then
Attention davej@redhat.com: this bug was fixed months ago. In FC2, package pcmcia-cs-3.2.7-1.8.2.2.src.rpm contains the corrected "serial" file. FYI.
thanks Steve, will close.
