AS/400 obtains the ASCII CCSID from the TCP/IP point-to-point configuration profile
that is being used for the SLIP session. You can configure this value in the Script
source information section of the profile, which is shown in “Use Connection
Dialog Script” on page 145. The default ASCII CCSID value is 00819 (ISO 8859,
part1 Latin Alphabet No.1). This ASCII CCSID covers most 8-bit languages that use
character set 697. All of the code points that are defined for ASCII CCSID 00819
support translations to the EBCDIC CCSID 500. This default covers most
translations. However, if you must use characters that are not supported in EBCDIC
CCSID 500 and ASCII CCSID 00819, then you must do the following:
1. Change the ASCII CCSID defined in the TCP/IP point-to-point profile that you
plan to use to a value that supports all of the characters that you require.
2. Create a connection script file with a CCSID that supports all of the characters
that you require and that is compatible with the ASCII CCSID that you have
selected.
Create the new connection script file as follows:
v Create the file with the desired EBCDIC CCSID:
CRTSRCPF FILE(lib/file) MBR(*NONE)
RCDLEN(128) AUT(*USE)
CCSID(your_ccsid)
v Copy the default connection script file information into the new file:
CPYF FROMFILE(QUSRSYS/QATOCPPSCR)
TOFILE(lib/file) FROMMBR(*ALL)
TOMBR(*FROMMBR) MBROPT(*ADD)
FMTOPT(*MAP)
Notes:
a. If you use FMTOPT(*MAP), AS/400 database attempts to automatically
translate the CCSID 500 code points in the default connection script file to
the equivalent code points of the new CCSID in the new connection script
file.
b. If you do not want this automatic translation of data from CCSID 500 to your
new CCSID, then use FMTOPT(*NOCHK).
c. If you do not want to copy or use the default connection script members,
then omit the step for CPYF. The SCRSRCPF step will suffice.
The ASCII and EBCDIC CCSID values that you select must be compatible CCSIDs.
If the CCSIDs are not compatible, AS/400 issues message TCP8373 'Unable to
convert data from CCSID &1' to CCSID &2' and ends the SLIP session. See
National Language Support
, SC41-5101 for information that can help you determine
which CCSID to use and which ASCII and EBCDIC CCSIDs are compatible.
Using SLIP with an Asynchronous Line Description
This section discusses how to create a SLIP connection profile that uses an
asynchronous line description.
Beginning in V4R2 support was added for the PPP line type. It is possible to create
a SLIP connection profile using either a PPP line description or an asynchronous
line description. While connection profiles using the older asynchronous line
description type can still be used, we strongly recommend that you use the new
PPP line type instead.
