File transfer protocol: The method you want to use to transfer files to
RBBS-PC ("upload") or to obtain files from RBBS-PC ("download").

TIPS:

1. You may want not to have a default transfer protocol if you use a
variety of protocols. Select the N)one option and RBBS-PC will ask for your
preferred protocol before each file transfer.

2. The protocol you want RBBS-PC to use must also be used by your
communications package.  Protocols available in RBBS-PC include Ascii (no
error checking), Xmodem, Xmodem/CRC, and Ymodem.  Others can be installed
by the Sysop, such as Kermit, Windowed Xmodem, Zmodem, and Batch Ymodem.
Xmodem is the most widely supported, but Ymodem and Zmodem are faster.

3. You can override the default my specifying the protocol on the same
command line as D)ownload or U)pload.  E.g. "D;SD.COM;C" downloads file
SD.COM in Xmodem/CRC no matter what the default protocol is.
