Optional FTP port in the range 0..65535.

The server name may be any legal Internet-server name, which
can be resolved by the iChip‘s DNS (Domain Name Server)
settings. The server name may also be specified as an absolute IP
address given in DOT form.
Specifies the FTP server‘s listening port. If not specified, port 21
(decimal) is assumed.
User‘s name string. This must be a registered user on the FTP
server. Some servers allow anonymous login, in which case
user=anonymous.
Password to authenticate user. If special characters are used, the
password must be specified within quotes. It is customary that
servers that allow anonymous login request an e-mail address as a
password.
Some FTP servers require an account in order to allow a certain
subset of the commands. In this case, the account name must be
specified when opening the FTP link.
Result Code:
@ The optional @ is used to flag the Force PASV mode. When @ is
specified, iChip only uses the PASV method when opening a data
socket to server for FTP data transfer.
I/ Upon successfully connecting to the FTP Server and
authenticating the user, a socket handle is returned. The handle
is used to reference the FTP session in all
following FTP commands.
