software modem init strings

[Lorenzo Prince]

sounds more like a problem with your ISP than a modem problem.  If it's
working fine except for large files, it's probably either your ISP or
something in your system before it gets to the modem.  Maybe you have set
a limit on the size of a file that can be transferred.  Check to see if
there is such an option in your configuration file for the modem.
