I use the PowerBook 1400c and PISON GOLD GSM modem card to connect my Telefinder Server, but I got the problem when both side connected. On user side I got the dialog box show "Waiting the hosts" and disconnect until the time limited for not sign on. But if I use the Zterm to connect the Telefinder Server, there are successful to login. I think that there should be the "AT" string problem on modem setting. Please help meto fix this problem. Thank you very much !!
