Page of GC20-1806-9 As Updated April 1, 1981 by TNL GN25-0834 VM/370 SUPPORTS SUBSYSTE! THE IBM 3800 PRINTING
New: Hardware Support VM/370 Release 6 supports the 3800 printing subsystem, a high speed,
non-impact, general purpose printer that
uses electrophotographic and laser
technologies to achieve printing speeds
up to 20,040 lines of copy per minute. VM/370 allows virtual machines,
including virtual VM/370, to attach the 3800 printer as a dedicated I/O device
and a spooling device. Release 6 also
supports the use of the 3800 with a
starter system before performing a full
system generation. In addition, the BACKSPAC, CHANGE, QUERY, SPOOL, and START CP commands have been modified to
support the features of the 3800 printer. (See "Section 2: Initiating VM/370 Operation"). SUPPORT FOR THE IBM 3850 MASS STORAGE SYSTEM Hardware and Programming Support VM/370 supports user minidisks on Mass Storage System 3330V volumes, where the
minidisk appears to the virtual machine
to be defined on a permanently mounted
IBM 3330-1 drive. MSS volumes may also be dedicated and
attached to a virtual machine as either 3330V or 3330-1 devices.
In addition, the new command DEFINE has
been provided to the user, enabling the
status of a 3330V volume to be
redefined. LOGON/LINK JOURNALING Program Feature Option VM/370 optionally supports the

recorded in a log file associated with
the named module. (See "Section 4: VM/370 Service Programs".) PASSWORD-ON-THE-COMMAND-LINE SUPPRESSION New: Program Feature Option VM/370 optionally supports passowrd
suppression. This feature gives the
installation the option to reject LINK
and LOGON commands in which the password
is entered from a virtual console on the
same line as the command. The AUTOLOG command is modified to force the user to
enter the password separately. Commands
entered from an EXEC or CMS module are
not affected. MONITOR COMKAND Function and Documentation
The functions of the MONITOR INTERVAL command have been expa nded to gi ve

console definitions at system
generation. If the primary console is
not operational during VM/370 IPL, the
list of alternate consoles is searched
in the order specified in the RIOGEN macro statement. The search is
continued until an operational device is
found. (See "Section 2: Initiating VK/370 Operation".)
