.SH NAME
|
|
ttyI, cui \- ISDN character devices
|
|
.br
|
|
.SH DESCRIPTION
|
|
.I ttyIx and cuix
|
|
are the character devices of the isdn4linux ISND driver package.
|
|
They can be used in the same way as the traditional serial
|
|
devices
|
|
.I ttySx
|
|
and
|
|
.I cuax.
|
|
The official major device numbers are
|
|
.I 43
|
|
for ttyI
|
|
and
|
|
.I 44
|
|
for cui. The minor device numbers start with
|
|
.I 0
|
|
and end with
|
|
.I 63.
|
|
|
|
The ISDN devices provide a modem emulation with a set of
|
|
traditional and some special AT commands. This provides easy use
|
|
together with almost all communication software that uses modem
|
|
commands:
|
|
.I minicom\c
|
|
(1),
|
|
.I seyon\c
|
|
(1),
|
|
.I XCept\c
|
|
(1),
|
|
.I uucico\c
|
|
(8) (Taylor UUCP),
|
|
.I mgetty\c
|
|
(8),
|
|
.I dip\c
|
|
(8),
|
|
.I pppd\c
|
|
(8) and more.
|
|
|
|
The line disciplines are handled by the kernel so that SLIP,
|
|
CSLIP and asynchronous PPP are possible.
|
|
|
|
The port speed of the
|
|
.I ttyIx
|
|
and
|
|
.I cuix
|
|
devices is always 64000 bps.
|
|
|
|
.SH AT COMMAND SET
|
|

|
|
.I AT commands
|
|
are supported by
|
|
