[질문]PPP 설정에 관한 조언을 구합니다.

리눅스 2대에서 PPP 서버와 클라이언트를 구현하고자 합니다.
클라이언트에서 dial후에 connect까지는 이루어집니다.
그런데 서버측에서 아래와 같은 결과가 나타납니다.
제가 보기에는 LCP 레벨에서 진행이 안되고 있는것 같은데요.. 제가 뭘
잘못했는지 알고 싶습니다.

클라이언트에서 실행은
/usr/sbin/pppd debug lock modem crtscts /dev/tts/2 2400 \
$LOCAL_IP:$REMOTE_IP \
noipdefault defaultroute connect $DIALER_SCRIPT
이고,

서버측의 내용은...

[root@localhost ppp]# pppd connect "chat -v -f /etc/ppp/rcv-chat" /dev/modem
2400 crtscts modem -detach -d kdebug 1

Serial connection established.
using channel 6
Using interface ppp0
Connect: ppp0 <--> /dev/modem

와 같습니다.
왜 'asyncmap 0'의 교환만 이루어지고 있는걸까요?

도움 말씀을 부탁드립니다.
