DSTAT function
Syntax: DSTAT(device-name [,EXCP=statement-label])
Discussion: The DSTAT function returns the current status of system devices.
The device-name is the name of the device to be checked. The device-name may be a string constant, a single-element string variable, a string array element, a string expression, or a string function.
Detailed information: DSTAT of the console
DSTAT of remote terminals DSTAT of a local printer DSTAT of a remote printer DSTAT of a spooler DSTAT of the system driver (X00) DSTAT of a gateway DSTAT of a directory DSTAT of the clock
DSTAT of the console:
Position Length Description/Values
============================================================
1 3 Partition
4 1 Type
0 = Monochrome
1 = Color
2 = Monochrome with flicker-free adapter
3 = Color with flicker-free adapter
4 = EGA/VGA/MCGA Monochrome
5 = EGA/VGA/MCGA Color
6 = TeleVideo
7 = AT&T
5 1 Option
01H = Force 80-column mode
02H = Force CR the same as Qantel
04H = Auto increment cursor
08H = FAST option enabled for all files
10H = Insert key is the same as Qantel
20H = Use expanded memory for all partitions
40H = Standard I/O for keyboard
6 1 Status
7 1 Foreground attribute (color)
8 1 Background attribute (color)
9 1 Invisible attribute (color)
10 1 Border attribute (color)
11 1 Entry attribute (color)
12 2 Base address
14 2 Current column and row
16 1 BIOS mode for 132-column
17 1 Current number of columns on screen
21 1 Returns "@01@" if the session is CometAnywhere
DSTAT of remote terminals:
Position Length Description/Values
===================================================================
1 3 Partition
4 1 Type
80H = dumb terminal
81H = TeleVideo terminal
82H = Ampex terminal
83H = Qantel VT3 terminal
84H = Qantel VT6 terminal
86H = QTerm workstation
F0H = Intermec bar code reader
FEH = RDI printer
FFH = ignored terminal
5 1 not used
6 1 Status
7 1 UART
8 1 Poll address
9 1 Terminal flag
!
80H OBP Terminal Lockout (Signal to PC that FG
processing loop is active on this terminal
and effectively locks out PC from changing
anything in the term table.)
!
20H Status Poll Hold Request (PC signals don't
do status poll on this terminal.)
!
10H Select Request (OBP should initiate a
select poll (data is in the buffer)
!
08H Buffer In Use Flag (OBP should not
initiate a data poll)
!
04H Data Poll Ack Request (PC has received the
data and the buffer is clear)
!
02H Reset Request (user has hit Escape)
!
01H Data Poll Request
!
10 1 Terminal process
!
Foreground Attention Needed
0 = IDLE - Dead terminal
1 = IDLE - Active terminal
2 = Status Poll Complete
8 = Waiting to send buffer to PC
9 = Finished select - OK
A = Finished select - NG
B = Data poll complete (ACK included)
!
UART is Working on this one
10H = Doing status poll
11H = Receiving data from terminal
12H = Sending data to terminal
13H = Retransmitting to terminal (1st
retransmit)
14H = Retransmitting to terminal (2nd
retransmit)
15H = Terminal reset in progress
DSTAT of a local printer (effective with build 319):
Position Length Description
=========================================
1 3 owning partition, if any
4 1 printer type in hex: 0=Local; 4=Windows
5 1 spool type in hex
To convert the type, take the HEXASC of the byte.
Look at the first character returned by HEXASC:
'6'=Auto-spool; 'A'=Exception spool; '2'=Non-spool
6 12 spooler alias name
18 237 pathname associated with the printer
DSTAT of a remote printer:
Position Length Description ========================================= 1 3 Partition 4 1 Type 5 1 Spool Type 6 1 Status 7 1 UART 8 1 Poll Address 9 1 Terminal Flag 10 1 Terminal Process 11 1 ROM Version
DSTAT of a spooler:
Position Length Description ===================================== 1 64 DOS path name
DSTAT of the system driver (X00):Position Length Description
===================================================
1 32 (reserved)
33 16 Network node name
49 2 Number of the of first partiton
on the node (byte-reversed hex)
51 2 Total number of partitions on
the node (byte-reversed hex)
53 1 "@01@" if the user has a COM license; "@00@" otherwise
DSTAT of a gateway:
Position Length Description ============================================= 1 3 Controlling partition 4 1 Gateway type (hex) 5 1 Gateway subtype (hex)
DSTAT of a directory:
Position Length Description ====================================== 1 3 Directory name 4 64 DOS path name
DSTAT of the clock:
Position Length Description =================================== 1 3 Clock name 4 10 Number of milliseconds that have elapsed since the Windows was started, up to 49.7 days.
