Chapter 4110
LS - Allocate Logical Terminal Storage
Format: LS,appl,label,size
appl application number (0 for general allocation)
label storage label (up to 6 ASCII characters)
size Bit 15 = 0 : allocate if new
Bit 15 = 1 : do not allocate
Bits 14-0 : size of storage in words
This command will find an existing storage for this application with
matching label and size. If the storage is not already allocated then the
command will allocate it if this is specified.
In either case, the command returns the logical terminal table offset of
the storage. This offset may be used in the LU command.
LU - Update Logical Terminal Table
Format: LU,ZLU,INDX,[len]
LU is allows the logical terminal table to be updated. Access is only
allowed into the User data portion of the table. The value INDX is the
offset into the table relative to the origin at 0. The index is in 16-bit
words. If an index value is given that is before the start of the User area
or beyond the end of the table, an error is returned. If the length plus the
offset will fall beyond the end of the table, an error is also returned.
If the [len] field is specified, then each 16-bit word is prompted one at a
time. When all words have been entered, the routine zltup is used to
update the logical terminal table.
MG - Move Logical Terminal Between Physical
Terminal Group
Format: MG,TZLU,NZLU
The terminal multiplexing capability of the ZCOM system allows
multiple logical terminals to link to a single physical terminal. This
command re-links an existing logical terminal (referred to by TZLU) to a
different physical terminal (referred to by NZLU). The source terminal
