p[1]x p[0]
The CCITT standard for a directory of the users of the
X.400 system. [See also X.400]
.
p[1]x p[0]
This is the CCITT standard protocol for a global system
for the exchange of electronic mail.
p[1]x p[0]
This is CCITT's 1984 update of X.25, also known as X.25
dialup. [See also X.25]
.
p[1]x dialupp[0]
See X.32.
p[1]x p[0]
This is a packet-switching protocol developed by CCITT.
It is used to carry large amounts of data at fast speeds over
leased phone lines. [See also X.32]
.
&
xfer
Short for transfer. It usually refers to file transfers.
[See also upload, download]

xmodem
p[1]xmodem kp[0]
This is similar to Xmodem/CRC, except it uses blocks
of 1024 bytes, rather than 128. It is faster than Xmodem, since
it needs to stop less often to check for errors. This is some-
times incorrectly called Ymodem. [See also protocol, Xmodem,
Ymodem]
.
p[1]xmodem crcp[0]
The same as Xmodem, but it has a 16-bit CRC instead
of the checksum, which makes it more reliable (it catches more
errors). [See also protocol]
.
A file transfer protocol developed by Ward Christensen
around 1977. It is fairly slow by today's standards, but was the
first widespread file transfer protocol. It uses blocks of 128
bytes, and after each block is sent, it sends a 1 byte checksum
to check for errors. If an error is encountered, the block will
be re-sent. Almost every communications program offers this
protocol. [Same as Christensen protocol]
. [See also protocol]
.
&
xoff
The CTRL-S character. This is often used to pause infor-
mation that is being sent. The information will be continued
when an CTRL-Q is received. [See also flow control, Xon]
.
&
xon
p[1]xon xoffp[0]
The flow control method using the Xon and Xoff charac-
ters. It is built into the software, not the hardware. [See
also Xon, Xoff, flow control]
.
The CTRL-Q character. This will sometimes continue paused
information. [See also flow control, Xoff]
