LAN Manager 2.0 Enhanced DOS Netpopup (72034)
This article was previously published under Q72034
SYMPTOMS
When a printer is temporarily out of service because the paper is
jammed, no paper is in the paper tray, or the printer is off-line,
normally a message is sent to the DOS or OS/2 workstation stating
that the printer is unavailable to complete the print job. However,
quite often a DOS Enhanced workstation will not display the message
concerning the unavailability of the printer.
CAUSE
The messenger section of LANMAN.INI contains a parameter called
sizmessbuf. On OS/2 workstations, the default value for sizmessbuf
is 4096 bytes. On DOS Enhanced workstations, the default value for
sizmessbuf is 256. When a message is received whose total size is
larger than the message buffer size, the message is dropped. The
printer unavailability message can easily exceed the 256-byte
buffer size.
RESOLUTION
Increase sizmessbuf to accommodate longer messages. Doubling the
default value to a 512 byte buffer should be sufficient for the
printer messages. Please note, however, that doubling this value
will affect the total available memory to the DOS workstation.
