<h4>
<b><u>OMS VME58 retry problem</u></b></h4>
Several errors in the OMS VME58 driver were found.&nbsp; All the errors
caused the same problem.&nbsp; Namely, erroneous retries occurred intermittently
when multiple axes were commanded to move on the same controller.&nbsp;
This error occurred because old position data was being passed back from
the driver after Done was detected.&nbsp; The erroneous intermittent retries
occurred more often when the Oms setup parameters called for a high frequency
(e.g., 60 Hz) "polling" rate and Oms interrupts were enabled.
(e.g., 60 Hz) "polling" rate and OMS board interrupts were enabled.
<h4>
<b><u>OMS Stop problem</u></b></h4>
A problem with issuing a stop command (via either the STOP&nbsp;or SPMG
field) was found with <b>all</b> OMS boards and <b>all </b>versions of
the OMS device drivers.&nbsp; The root cause of this problem is a statment
in the OMS manual <i>that is not entirely correct</i>; the AC and VL commands
are not completely queued.
