An Overview of File Transfers
and Fax Operation
This section does not describe how to transfer and receive files
and fax messages – your communications and fax software and
their supporting documentation define this process. Its purpose
is to make you aware of the basics involved when using these
forms of communications with the KeepInTouch Card modem.

File Transfers

Two terms essential to file transfers are download and upload.
A download occurs when you want to receive a file from a host
site. An upload occurs when you want to send a file to a host
site. However, before you can do this, the following must occur:
G
Your modem and PC must be configured for modem
operation before executing your communications
software.
G
Your modem must be online with another modem.
G
You must have communications software that is
operating and in terminal mode.
G
Determine whether you want to upload or download files.
G
Verify that the character format (7 data bits, odd parity,
1 stop bit; 8 data bits, no parity, 1 stop bit; and so on) is
the same for both the local and remote modems.
G
Select a file transfer protocol (ZMODEM, YMODEM,
XMODEM, Kermit, and so on) that is compatible with
your communications software and remote system.
Some protocols require simultaneous actions at both
ends of the link to start a transfer, while others permit
initiation of the transfer from one side only.
