Hi All. I am trying to get a mobile scanner Motorola MC32N0 (next generation in MC3000 Series) working on a PC which is running Ubuntu 8.04, and another PC with Ubuntu 14.04. But I have not succeeded after trying and investigating a long time. I have two oldest models of Motorola mobile scanner working fine: MC3090 and MC3190. MC3090 with Windows CE 5.0 MC3190 with Windows Mobile 6.5 MC32N0 with Microsoft Embedded Compact 7. File PPP options (optionsttyUSB0.ce): /dev/ttyUSB0 10.1.20.1:10.1.20.2 asyncmap 0 local lock lcp-echo-interval 3 lcp-echo-failure 3 lcp-restart 1 lcp-max-terminate 4 unit 0 mtu 168 mru 168 connect "/usr/sbin/chat -v -t 5 'CLIENT' 'CLIENTSERVER\\c'" noauth -detach debug dump kdebug 7 Command: /usr/sbin/pppd ttyUSB0 file /etc/ppp/peers/optionsttyUSB0.ce The output is identical for all models to the time the devices incorporate its IP address -> (*) MC3090 output ... rcvd [IPCP ConfAck id=0x2 <compress VJ 0f 01> <addr 10.1.20.1>] rcvd [IPCP ConfReq id=0x4 <compress VJ 0f 00> <addr 10.1.20.2>] sent [IPCP ConfAck id=0x4 <compress VJ 0f 00> <addr 10.1.20.2>] local IP address 10.1.20.1 remote IP address 10.1.20.2 rcvd [CCP ConfAck id=0x3] (*) sent [LCP EchoReq id=0x1 magic=0x76ec1483] rcvd [LCP EchoRep id=0x1 magic=0x0] sent [LCP EchoReq id=0x2 magic=0x76ec1483] rcvd [LCP EchoRep id=0x2 magic=0x0] MC32N0 output ... rcvd [IPCP ConfAck id=0x2 <compress VJ 0f 01> <addr 10.1.20.1>] rcvd [IPCP ConfReq id=0x4 <compress VJ 0f 00> <addr 10.1.20.2>] sent [IPCP ConfAck id=0x4 <compress VJ 0f 00> <addr 10.1.20.2>] Cannot determine ethernet address for proxy ARP local IP address 10.1.20.1 remote IP address 10.1.20.2 rcvd [CCP ConfAck id=0x3] (*) rcvd [LCP TermReq id=0x1] LCP terminated by peer Connect time 0.1 minutes.
