Yes. You can use SET TCP/IP DOMAIN to set your PC's full name.
But the value of this setting is known only to Kermit itself, and it
is used for only one purpose: to turn "nicknames" into fully qualified
domain names (FQDN). For example, if your network is called foo.bar.baz
and your PC is called oofa, then its FQDN is oofa.foo.bar.baz.
If you say "set port tcp blah", Kermit sends a query to your name server
for "blah". If it doesn't get a satisfactory response, then it uses
your SET TCP DOMAIN value to try to make an FQDN. Normally you would
have your TCP DOMAIN set to your network name rather than your PC's FQDN,
so Kermit would try:
blah (no match)
blah.foo.bar.baz (works)
If you set your TCP DOMAIN to your PC's own FQDN, then Kermit tries:
blah (no match)
blah.oofa.foo.bar.baz (no match)
blah.foo.bar.baz (works)
Both ways work, but the second way takes a bit longer.
The best way to set your TCP/IP parameters is from an organizational
BOOTP server. Then the only command that you (or anybody else) needs
for Kermit TCP/IP setup is SET TCP ADDRESS BOOTP. The advantages of
this approach are so overwhelming that every site should read about
them and set up a centralized bootp database. Maybe your site has one
already and you only need to be registered in it.
MS-DOS Kermit 3.13 and later support BOOTP at RFC 1395, which allows
the domain name to be downloaded to the PC from the BOOTP database.
The original BOOTP specification (and BOOTP servers and databases based
on it) did not include the domain name.
