Module id number: CSS/311
--------------------------
Module name: TTY DRIVER
-----------------------------------
Actual release: 11.04 Release date: 850517
----------------------- --------------------
Previous release: 11.03 Release date: 850403
----------------------- --------------------
New facilities:
---------------
>>11.01<<
1101 FP/840810 Able to use a MIC.
1101 TLM/841101 The TTY driver now in MX systems awaits a signal
during initialization, to avoid race for the console
interface with ROOT.
MX ROOT version 0202 sends this signal when it
has finished system initialization.
As a consequence of this, This TTY driver cannot
be used in MX systems with older ROOT versions.
The driver, itself, determines from the existance
of a MIC, when the IV mod 64 = #3D, wheter to use
MIC instructions, or MAP instructions.
>>10.01<<
Statistics gathering is noq included.
Five 32-bits counters are updated:
Number of write requests
Number of read requests
Number of abort requests
Number of bytes written
Number of bytes read
>>09.01<<
After being edited, the remainder of the line is
outputted entirely. This produces the same screen
image, as when the line was originally typed.
(PR 739).
A new mode has been introduced in this mode the
driver will not echoe nor interpret any input
character.
This mode is entered (for one process), if exactly
one character is output. and the value of this
character is #80.
The mode is left temporarily, when output from an-
other process is processed or a Break-condition is
encountered. In such cases, the next request from
the process using the new mode, will be answered
with a completion code of #680.
The mode is left for good, when a Dismantle command
is received from the process using the mode. (PR 895).
If there are no (more) TAB stops defined, the cursor
will not be moved. (PR 928).
Changes:
--------
>>11.04<<
Part of readit, handling MIC is now executing disabled.
>>09.01<<
The device address (iv) must now be sent to the driver
in the initialization message instead of device address
times four. This change was necessary in order to be able
to execute on the CR80-MX.
Access to and through transfer lists are now performed
by calls to the module CSS/357. This change was imple-
mented in order to make it possible to use the same dri-
ver for AMOS, XAMOS, and MX-AMOS.
If the received device address equals #3D, the driver as-
sumes that it has to use the serial interface of a CR80-
MX step 1 MAP. Otherwise it automatically finds out whe-
ther the interface is an AV/24 or an SCM.
All reservation messages are now answered with the pro-
gram page of the driver. Further, the linelength and
the mode bits (echoe, vdu, await terminal ready, wait
200 ms after nl, and print FF) may be redefined.
Errors corrected:
-----------------
>>11.03<<
Error in typeit on MX Type 2 corrected.
Error in readit on (X)AMOS corrected. (PR no. 1262).
>>11.02<<
Error in conversion of MIC status into old fashioned
V24 status corrected.
>>10.01<<
Initialization messages are now also treated when received
during execution of other commands.
Reported errors, not corrected:

CPECRs implemented in current release:
