Hi, All!
I have very strange problem with user-level ppp. ppp always see carrier on
my modem. All other software works perfectly (mgetty, FIDO mailer
qico).
Here are details:
Motherboard is SiS496, CPU i486DX4-100, 16Mb of RAM.
Sportster 33600 internal ISA is installed as COM2 (motherboard's
COM2 is switched off). I have next lines in my kernel config:
device sio0 at isa? port "IO_COM1" tty flags 0x10 irq 4
device sio1 at isa? port "IO_COM2" tty flags 0x10 irq 3
Kernel found devices:
sio0 at 0x3f8-0x3ff irq 4 flags 0x10 on isa
sio0: type 16550A
sio1 at 0x2f8-0x2ff irq 3 flags 0x10 on isa
sio1: type 16550A
mgetty works perfectly:

01/20 20:58:13 aa1 check for lockfiles
01/20 20:58:13 aa1 locking the line

01/20 20:58:16 aa1 mdm_send: 'AT+FLI="7 812 1072343"' -> OK
01/20 20:58:16 aa1 mdm_send: 'AT+FCC=1,5,0,2,0,0,0,0' -> OK
But user-level ppp could not use port /dev/cuaa1!
It always see carrier on it:
ppp ON freebsd> set log local +chat +phase +connect
Phase: bundle: Establish
Phase: deflink: closed -> opening
Phase: deflink: Connected!
Phase: deflink: opening -> dial
Chat: deflink: Dial attempt 1 of 1
Phase: deflink: dial -> carrier
ppp ON freebsd> Phase: deflink: /dev/cuaa1 doesn't support CD
Phase: deflink: carrier -> login
Chat: Send:
Chat: Expect(15): login:
I could say more: if I setup ppp to use /dev/cuaa0 (which is empty),
ppp will find Carrier too:
ppp ON freebsd> set device dev/cuua0
Phase: bundle: Establish
Phase: deflink: closed -> opening
Phase: deflink: Connected!
Phase: deflink: opening -> dial
Chat: deflink: Dial attempt 1 of 1
Phase: deflink: dial -> carrier
ppp ON freebsd> Phase: deflink: /dev/cuaa0 doesn't support CD
Phase: deflink: carrier -> login
Chat: Send:
Chat: Expect(15): login:
Simple program, which call ``ioctl(d,TIOCMGET,&flags)'' could not
find any carrier.
