BTC modem setup in Sarge
Hello, debian-user.
I have an internal hardware modem BTC 1879 33600. The modem jumper is
set on COM3
During boot BIOS writes in ISA/PNP devices list:
DEVICE NO IRQ DEVICE
----------------------------------------------
01 10 33.6K PNP-16 MODEM
In WinXP it works on COM3, detected as "BTC 1879 33.6K Internal PNP-16
Voice,SP,FAX Modem"
Used resources is: IRQ: 10, input/output ports: 02E8-02EF
Under Knoppix modem works on /dev/ttyS3:
# setserial /dev/ttyS3
irq 3, uart 16550A, port 0x02e8
And it works!
But under Debian Sarge it doesn't work :(.
Nor /dev/ttyS2 (as COM3) not /dev/ttyS3 (as in Knoppix)
I have a Debian Sarge (July 2004), kernel 2.4.26 original
# setserial /dev/ttyS3
ttyS3: LSR safety check engaged!
irq 3, uart 16550A, port 0x02e8
Message "LSR safety check engaged!" is a visualisation of a problem
For instance, wvdial output is the following:
golden@localhost:~$ wvdial
--> WvDial: Internet dialer version 1.54.0
ttyS3: LSR safety check engaged!
--> Cannot open /dev/ttyS3: No such device
ttyS3: LSR safety check engaged!
--> Cannot open /dev/ttyS3: No such device
ttyS3: LSR safety check engaged!
--> Cannot open /dev/ttyS3: No such device
On /dev/ttyS2 wvdial output is the following:
golden@localhost:~$ wvdial
input/output error
Tries to set IRQ 10 with setserial fail:
# setserial /dev/ttyS3 irq 10
ttyS3: LSR safety check engaged!
In attach see dmesg parts from knoppix & sarge
