comms/birda and ppp: Chat script failed

[Alexander_(_dot_)_Farber_(_at_)_t-online_(_dot_)_de (Alexander Farber)]

Hi,

could someone please share his ppp setup for birda?

I'm using Nokia 9210 "Communicator" mobile and IBM Thinkpad 
T22 laptop, whose infrared device appears in the dmesg output 
as: pccom1 at isa0 port 0x2f8/8 irq 3: ns16550a, 16 byte fifo

I've installed birda from -current ports and have added the
user "alex" to the "dialer" group - so that I can access tty01.
Then I try to run "ppp -foreground d2-irda" using this ppp.conf:

default:
        set log Phase Chat LCP IPCP CCP tun command
        allow users alex

d2-irda:
        # shell ircomm -Y -d -r /dev/tty01 -v 1 -y /dev/ptyp6
        bg ircomm -d /dev/cua01 -v 1 -y /dev/ptyp6
        set device /dev/ttyp6
        set speed 115200
        set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \"\" AT OK-AT-OK ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT"
        set phone 0049172229000
        set authname d2
        set authkey d2
        set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0
        add! default HISADDR
        enable dns

The laptop seems to connect to the mobile phone, 
because I see the following output:

thinkpad:alex {115} ppp -foreground d2-irda
Working in foreground mode
Using interface: tun0
query completed
discovered EP, address=66886068, hints=PDA, Modem, Telephony, IrCOMM, IrOBEX
query completed
115200 baud
LAP connected
comm connected

Unfortunately in the ppp.log (pasted below) I keep seeing the
following "chat script failed" warning even though I tried using 
cua01 and tty01 and also tried out -Y and -r switches for ircomm:

Dec 29 16:00:33 thinkpad ppp[16252]: tun0: Chat: Send: AT\^M 
Dec 29 16:00:33 thinkpad ppp[16252]: tun0: Chat: Expect(5): OK 
Dec 29 16:00:38 thinkpad ppp[16252]: tun0: Chat: Expect timeout 
Dec 29 16:00:38 thinkpad ppp[16252]: tun0: Warning: Chat script failed 

Does anyone have any advices or can share the config files?

What's the purpose of "ircomm -r"? I always see Send: AT\^M in the log.

Regards
Alex
