Conect a modem using com port

Hi  All

I have been scratching my head on this for a bit.. I am using Kannel..

I am trying to connect a modem to my com port and an unable to get it
working.. I know the modem is working as it works on windows and linux..

My dmesg for com displays the following

-bash-2.05b$ dmesg |grep com

builds <at> b7.netbsd.org:/home/builds/ab/netbsd-5-0-2-RELEASE/i386/201002061851Z
-obj/home/builds/ab/netbsd-5-0-2-RELEASE/src/sys/arch/i386/compile/GENERIC

com1 at isa0 port 0x2f8-0x2ff irq 3: ns16550a, working fifo

I have disabled tty00 in my /etc/tty
ttyE2   "/usr/libexec/getty Pc"         vt220   on secure
ttyE3   "/usr/libexec/getty Pc"         vt220   on secure
#tty00  "/usr/libexec/getty std.115200" unknown on secure
tty01   "/usr/libexec/getty std.9600"   unknown off secure

Still unable to connect. I see the TX light on the modem blink when I try to
connect to the modem

Re: Conect a modem using com port

Maybe use /dev/dty00 as an outgoing device?

RE: Conect a modem using com port

No luck using /dev/dty00 (changed to dty01 and did not work either)

The modem has TX blinking..

Did you try a different bitrate? To start with, did you try to talk
to the modem using "cu"?
