SIOCSIFFLAGS: Input/output error

SIOCSIFFLAGS: Input/output error

[Phil]

Hello,

I'm about to do the "Grey Nomad" thing and hit the road in our motorhome. I 
thought it might be handy to have a packet system to play with.

I'm using a USB to serial converter which works without any problems with 
other serial devices, however, I get the error message shown on the subject 
line when I attempt to use my Baycom modem. This is the init script that I've 
used for years, but with /dev/ttyS0 instead of ttyUSB0:

setserial /dev/ttyUSB0 uart none
modprobe baycom_ser_fdx
sethdlc -p -i bcsf0 mode "ser12*" io 0x3f8 irq 4
ifconfig bcsf0 up
ifconfig bcsf0 10.0.0.1
axparms -setcall bcsf0 VK4BVM

I can see that the lines that begin with "ifconfig bcsf0" are the culprits. I 
have /etc/ax25/parms/bcf0/. What am I missing?

Phil.

Baycom serial is not a serial device. It uses the serial port in a very 
non-standard way to do "clever" bit banging and emulate synchronous 
serial communication. That is why it only works with ports that are 
100% hardware compatible with the standard PC UART (8250, 16450, 16550).

I think it's pretty safe to say that you will *not* find a USB/serial
converter that would work with the Baycom serial modem and its
kernel driver.

Another option that might work better than a USB/serial convertor would 
be a serial PCMCIA interface, they are more likely to be compatible at a 
hardware level.

Thanks for the replies, both on and off the mailing list. I thought about this 
a bit more after I posted my query and thought that the converter had to be 
the problem.

It looks like my old faithful Baycom modem will join the rest of my stuff in 
storage. If packet radio grabs my attention again I might have to buy a TNC 
after all.

There's always the soundmodem ..

Also the uTNT, which uses a USB connection, does KISS and is reasonably
priced <http://www.elcom.gr>.
