Solution
Press Alt-F4 on the host computer and then warm boot the
reader. A lockup occurs when both these conditions are true:
• An active Intersvr connection to the JANUS reader exists
when the reader reboots. The reader's default CONFIG.SYS
file installs Interlnk automatically when the reader is
connected to COM1 of the host computer and the host is
running Intersvr.
• The reader's CONFIG.SYS and AUTOEXEC.BAT install a
combination of device drivers, DOS options, TSRs, and
applications that absorb the majority of available conventional
memory.
When both conditions exist, there is not enough space for your
software configuration to coexist with the Interlnk device driver.
The reader attempts to allocate memory that is not available, and
a lockup may occur.
To prevent the lockup, press Alt-F4 on the host computer or
break the serial connection between the reader and host
computer before the reader reaches the DOS initialization step of
the warm boot.
When you exit Intersvr on the host computer or break the serial
connection, the Interlnk device driver will not detect
INTERSVR.EXE, and Interlnk will not be loaded into the reader's
memory.
These DOS commands are not supported on the reader:
DOSSHELL.*
