# x3270(1)

IBM host access tool

## NAME

x3270 - IBM host access tool

## SYNOPSIS

**x3270** \[*options*\] \[*host*\]\
 **x3270** \[*options*\] *session-file*.x3270

## DESCRIPTION

**x3270** opens a telnet connection to an IBM host in an X window. It implements RFCs 2355 (TN3270E), 1576 (TN3270) and 1646 (LU name selection), and supports IND$FILE file transfer. The window created by **x3270** can use its own font for displaying characters, so it is a fairly accurate representation of an IBM 3278 or 3279. It is similar to *tn3270*(1) except that it is X11-based, not curses-based.

## WIKI
