Eurotel CardPhone PCMCIA Modem not working with serial_cs
Last modified: 2015-01-04 17:06:35 EST
The serial_cs driver in /drivers/serial does not work with the Eurotel
CardPhone PCMCIA Modem. The problem can be traced down to the PCMCIA
card claiming to have an IO window of 16 rather than 8 bytes, which
the driver skips. The fix below works for me, although I do not claim
to understand PCMCIA enough to be sure it does not break other cards ...
# diff serial_cs.c.new serial_cs.c.old
< if ((cf->io.nwin > 0) &&
< ((cf->io.win.len == 8) ||
< (cf->io.win.len == 16)) &&
> if ((cf->io.nwin > 0) && (cf->io.win.len ==
Version-Release number of selected component (if applicable):
Steps to Reproduce:
This might be a safer approach - look for 8port entries and then for
16. Let me know if something like this also works
