Default modem holds line..





Ambient Ham chipset Modem ATI diagnostics OK.Disabled 'wait for dial
tone' and It dials but it cannot connect and after that it just
'arrests' the line; tried at&t1 in Hyper terminal-modem 'connects' at
115200 and spits some characters, ath/h1 ok; checked line-around 50
volts but when modem plugged in, it goes to 13v, desoldered MOV is ok
but low resistance measured at it's modem board contacts;bridge output
goes to darlington...?; as mentioned-in or out of the PC when I plug in
the line first you can hear the dial tone &then after 1-2 min. modem is
holding the line
