We have a customer that is using a Dell Poweredge 1600sc running Sco Openserver 5.0.6 using a USR modem 5686e . We can dial in no problem and send data till the cows come home but when we try to pull data back it looks like it is pulling OK and at different points we get this error "The file transfer is active, but sector XX was received twice. The duplicate sector has been discarded." and it stops transferring data. We have tried 2 init strings: ats0=002&a0&k0&m0&d0&h1&i1&n6&w0&w1 and at&f&k0&m0&a0&n6&u6&w. We have slowed our modem speeds down and remove error correction and data compression with no luck anyone have any ideas?
