Hi,

TA. 
Our server is connecting, but not prompting username. 
I am connecting as below.


I have run pppd as follows

/usr/sbin/pppd /dev/ttyS0 115200 passive connect \
 /etc/ppp/script/ppp-on-dial

/etc/ppp/script/ppp-on-dial is chat script as follows


#!/bin/sh
#exec chat -v                           \
        TIMEOUT         60              \
        ABORT           '\nBUSY\r'      \
        ABORT           '\nNO ANSWER\r' \
        ABORT           '\nRINGING\r\n\r\nRINGING\r'    \       
        ''               \rAT                           \
        'OK-+++\c-OK'   ATH0                            \
        TIMEOUT         40                              \       
        OK              ATD8210020                      \
        CONNECT         ''                              \
        sername:--sername: ACCOUNT                      \
        assword:        PASSWORD
