The X command can be used to set a variety of options.  If no argument is
given, X simply toggles and displays the new Expert status. When Expert
status is set, the initial connect messages are replaced by a compatibility
identifier line (currently [MSYS-ver-$]) and the command prompt is simply >.

     If a number is given after X, this is the number of lines to display
for a R command before asking More? To continue displaying the current
message when More? is sent press return. To abort the message, type N and
then return. This facility has been added to prevent a long message from
scrolling off your screen faster than you can read it. Experiment with
different values until you find one that pleases you. 
To not use this facility, set the number of lines to zero. Examples:
X 20  (pause after every 20 lines)       X 0  (don't pause ever)

XF     Set "fast" mode: BBS will put more than one line per packet
XS     Set "slow" mode: BBS will put only one line per packet.
Note: If you have very good path to bbs, use XF. If you have a poor
path to bbs, use XS since short packets make it through easier.
