By getting your Devices and Systems files in sync with each
other or by dialing direct.

Thee are three ways to dial out using cu.  The first needs a
"Direct" entry in /usr/lib/uucp/Devices for the port you
want to use.  It might be:

Direct tty1a - 57600 direct

If that's true, and /dev/tty1a is owned by cu, you can then
say:

cu -ltty1a dir

and you'll be connected to the modem and can type atdt etc.

The other way uses dialers.  You'd have an ACU entry,
something like this:

ACU tty1A - 57600 atdialUSR

With that entry, you could say:

cu 18005551212

(though most of us would use "cu -x9" so we could watch the
connection).

The final way is to have an entry in your Systems file. 
This would look like

world Any ACU 38400 16177399753 ogin: xxx/rppp sword:
xxxxxxxx

(the login and password info is NOT used by cu but is used
by ppp)

If I had the above entries, I'd get that No Devices
available message if I said

cu -x9 world

The reason is that speeds don't match.  The Devices file
says 57600, but Systems says 38400.  They need to match-
change one or the other.

Another thing to know is that there is nothing magic about
ACU- that can be any label you like, but again, it's got to
match in both files.  Having your own labels can be useful
when you need particulat behavior for certain sites, such as
only using a specific modem.  If you had, for example

ACU tty1A - 57600 atdialUSR
ACU tty2A - 57600 atdialUSR
SPC tty1A - 57600 atdialUSR

in Devices, and 

world Any ACU 57600 16177399753
europe Any ACU 57600 15555555555

in Systems, then a "cu world" would use either tty1A or 2A,
whichever was available, but a "cu europe" would only use
tty1A.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
