Hello,
I have a modem on my home computer on com2:
ttyS01 at 0x02f8 (irq =3D 3) is a 16550A
root@md:~# setserial -a /dev/ttyS1
/dev/ttyS1, Line 1, UART: 16550A, Port: 0x02f8, IRQ: 3
Baud_base: 115200, close_delay: 50, divisor: 0
closing_wait: 3000, closing_wait2: infinte
Flags: spd_normal skip_test
It works just fine for transferring data. Some info about it:

ATI4 gives:
PARALLEL-16550 * EXT-HYB * V34 * V42bis * TIES * CLASS1 FAX * CLASS2 FAX
This is a Sierra SQ3465 voice modem with a maximum speed of 33600bps for da=
ta and 14400 for fax.
The problem that I encountered was when I tried for the first time to send
a fax. I tried to dial manually and a sequence of commands like:
at+fclass=3D2
atdp7777777
will give me a bunch of strange characters after connect instead of a norma=
l answer
followed by OK. I thought then that I have a problem with my hardware(ie
modem) be than I noticed that the same configuration and the same sequence
of commands has a normal behavior in a MS-DOS application like term95.exe
(from Norton Commander 5.0).
I tried to use a 2.0.33 kernel(compiled with egcs 1.0.2 or with gcc 2.7.2.3=
). The
modem has the same symptoms with 2.1.103 and 2.1.104pre1(compiled with gcc =
2.7.2.3).
The fact that this configuration is working properly in MS-DOS with a
simple program (which doesn't use hardware/software flow control or any
other special features) makes me to believe that there is a bug in kernel or
this modem has something broken.
My configuration is:

PS: The kernel 2.1.104pre1 looks stable to me. I'm running it for 6 hours a=
nd I had no problems 'till now(gcc+netscape+ppp+Xwindows).
