Lets take the easy part of this first. None of the UARTS supported
by OpenVMS have a 14400 speed in the list of known speeds. For modems
that work at 14400 you should set the line to 19.2K baud. If you have
a DHQ11 that will accept a 38.4K then you can try running the line at
38.4K. Not all the DHV/DHQ style controllers will work at 38.4K.
Also if you run at 38.4K you will have to have the alternate type-ahead
buffer enabled, and the size should be about 900 characters.
The other half of this is much harder, you do not state what kind
of controller is being used. The TX designaition is used for several
drivers and easily 12 different terminal controllers built by Digital
and any number of third party look alikes. We need to know a bit more
about the line when it gets stuck. They type of controller, an output
from show terminal when it is stuck would be helpful. Also the
following information from SDA is helpful.
sda> set output tt_capture.txt
sda> read sys$system:sysdef
sda> read sys$system:sys
sda> show dev tx??
.
. Lots of output here
.
sda> format ucb
.
.
. even more data
.
.
sda> exit
One thing that you can try is to see if somehow the type ahead
characteristic got changed, or if secure server got set for the line.
