IBM AS/400e Computer Hardware User Manual


 
The old default character mapping tables, QTCPEBC (see Table 66 on page 528)
and QTCPASC ( Table 67 on page 528), remain on the AS/400 system. These
mapping tables can be used by specifying the following:
v For TELNET ASCII line mode, specify QUSRSYS/QTCPASC for the TBLVTOUT
parameter and QUSRSYS/QTCPEBC for the TBLVTIN parameter.
v For FTP client, specify QUSRSYS/QTCPASC for the TBLFTPOUT parameter and
QUSRSYS/QTCPEBC for the TBLFTPIN parameter.
v For FTP server, specify QUSRSYS/QTCPASC for the TBLFTPOUT parameter
and QUSRSYS/QTCPEBC for the TBLFTPIN parameter. The FTP server must
be ended and started for this change to take effect.
TCP/IP supports both ASCII and several variations of EBCDIC character sets. The
tables in this section describe the character sets and the mapping between them.
Table 62 and Table 63 describe the EBCDIC character set and code page that are
shipped with the system.
Note: Table 62 and Table 63 are used only if ASCII-to-EBCDIC or
EBCDIC-to-ASCII mapping tables cannot be found or generated based on
the current national language. Refer to the
International Application
Development
for the 037 (EBCDIC) code page.
