Many thanks for these informations. I can write a patch that does:

PWD -->
<-- 257 "QGPL" is current library.

If the initial directory character is not a '/', then
        SYST -->
        <-- 215 OS/400 is the remote operating system. The TCP/IP
version is "V5R4M0".

        If the string contains " OS/400 ", then
                SITE NAMEFMT 1 -->
                <-- 250 Now using naming format "1".
                PWD -->
                <-- 257 "/QSYS.LIB/QGPL.LIB" is current library.

This will not add any protocol overhead for servers that are not on
OS/400, or that start in name format 1 mode.
In addition, if some other "strange" servers/OS are discovered in the
future, the infrastructure to deal with would already be in place.

Daniel, would you accept such a patch ?

Kind regards,
Patrick
