OpenVMS Terminal-related Consulting Services
Since founding the firm in 1978, Dr. Gezelter has worked extensively
with terminal handling and related communications. His activities have
included:
-
architecting, designing, implementing, and maintaining command
procedures to configure applications software and physical devices
during the OpenVMS system startup (and applications startup)
processes
-
architecting, designing, implementing, and maintaining forms
management APIs and related libraries using the extended
functionality of the OpenVMS Terminal Driver
(IO$READVBLK|IO$M_EXTEND)
-
architecting, designing, implementing, and maintaining utilities to
monitor the operation of large numbers of terminals. In one notable
case, such an application (implemented using
Asynchronous System Traps, known as ASTs)
was so efficient that it accumulated infinitesimal CPU time over
a period of several days (the system operators -- on a MicroVAX II --
actually reported the program as broken -- insufficient CPU time used
over a multiple day period)
-
implementing numerous DCL procedures to address a wide range of client
application and system management requirements
-
speaking on terminal management and programming on OpenVMS and related
products at DECUS Symposia in the United States, Canada, Switzerland,
France, and Turkey
