I am working with a cardbus modem that is somewhat buggy. Unfortunately, I
dont have much documentation for its AT Command set (its a GPRS modem) and
at&f or atz does not seem to reset it properly when it goes "wonky". The
only way is to pull it out and put it back in. Unfortunately, I want to
remotely deploy this device so I cant physically do that. A reboot seems
to work, but thats not the greatest thing to do either.
dmesg shows
cbb0: <RF5C476 PCI-CardBus Bridge> mem 0xe6400000-0xe6400fff irq 12 at
device 10.0 on pci0
cardbus0: <CardBus bus> on cbb0
pccard0: <16-bit PCCard bus> on cbb0
cbb1: <RF5C476 PCI-CardBus Bridge> mem 0xe6405000-0xe6405fff irq 5 at
device 10.1 on pci0
cardbus1: <CardBus bus> on cbb1

This is a RELENG_5 box from 5.3-STABLE FreeBSD 5.3-STABLE #0: Wed Dec 22
Thanks in advance,
