ECO KIT SUMMARY:

An ECO (patch) kit exists for YEDRIVER and DZDRIVER on OpenVMS VAX
V5.3 through V5.5-2. This kit addresses the following problems:

For the DZDRIVER and YEDRIVER:

o Random extra characters (usually the lowercase 'h') are
transmitted on terminal lines.

This problem is fixed in OpenVMS VAX V5.4-3.

For the YEDRIVER only:

o Data loss may occur on MicroVAX II and VAXstation 3100 TTA2
ports due to limited modem signal capabilities. The old check
for the CTS (Clear To Send) modem signal was once per second.
The YEDRIVER now checks the state of the CTS modem signal
before each character is sent so data will not be lost if the
CTS signal has been dropped.

o TT ports on a MicroVAX II or VAXstation 3100 may lose data
characters received at higher baud rates (9600 or 19200). No
data overrun errors or framing errors are returned when this
condition occurs.

o The TT ports on a MicroVAX II or VAXstation 3100 can only
support a maximum baud rate of 19200. If the user tries to
set the baud rate to 38400 (e.g., SET TERMINAL/SPEED=38400),
the YEdriver sets the baud rate to 50. If the user displays
the terminal characteristics from another terminal using the
DCL command 'SHOW TERMINAL TTAn', the speed is displayed as
at 38400 even though the baud rate has been set to 50.

o Using the SET TERMINAL qualifier /COMMSYNC on a VAXstation
3100 or MicroVAX II TTA2 port caused the port to hang. This
port is the only port on the workstation that has modem control
signals.
