Changes since TeleReplica version 3.9
4.26 Modified the IRQ line detect code in TRHOSTIN so that it would
recognise serial ports on IRQ8-15.
4.25 Re-compiled with Turbo C++ 1.01 to avoid a problem apparently
due to extended memory conflicts when TRHOST was compiled
with Borland C++ 3.1.
Updated address for correspondence.
Added a day-of-week check into TRCHECK.
Modified TR to ignore control-break, since this was being
falsely triggered on some computers. For those needing to
use control-break, it is now an explicit option in the local
TR menu.
4.24 Added a utility (TRSPEED) to allow the screen update speed to be
set independently of the actual DTE/DCE speed.
Made TR strip the parity bit before displaying data while
operating in "dumb terminal" mode prior to establishing a
session.
Made TR continue to operate in "dumb terminal" mode after a
carrier is detected until a recognizable command is received
from TRHOST (this means that connect messages get displayed
in full).
4.23 Allowed use of 25x80 text pages other than 0.
4.22 Changed the version number to stop people thinking that version
3.9 was a later version than 3.22!! 4.22 and 3.22 are the same!
3.22 Modified the way TRHOST's private mode works to avoid problems
with CapsLock, NumLock and ScrollLock. Previously some PCs
experienced a delay of 20 seconds or so while the BIOS waited
for a keyboard interrupt that would never occur since TRHOST
had disabled all keyboard interrupts. Now the keyboard interrupt
is briefly enabled after any of these keys has been pressed.
Updated various sections of the documentation, including
specifying a bank account for direct funds transfer for
registration.
Modified the file transfer status window to report throughput
in characters per second rather than percentage efficiency.
3.21 Added the capability to limit the length of a session (useful
for toll-free numbers).
Increased the buffer size to suit higher speed modems (this
only affects screen refresh time and only at speeds above
2400 bps).
Added to TRHOSTIN the ability to scan the PC's hardware looking
for installed COM ports and locating the associated IRQ lines
(from IRQ2 to IRQ15 inclusive). This makes it considerably
easier to install for things like internal modems with
non-standard IRQ lines.
3.20 Moved control of host printer redirection into TRHOST/TRHOSTIN/
TRHOSTC (this now makes it possible to install TRHOST so that
print redirection is off by default).
Corrected a problem that caused \\ to be reduced to just \ and
then to nothing when strings were being edited in TRHOSTIN.
Added section 0 to TR.DOC to provide a quick path to getting
the package up and running.
Made sending an initial "at&f" to the modem optional in
TRMODSET.
3.19 Added support for IRQ8-15 for 16-bit I/O cards.
Added TRHOSTC.EXE to modify TRHOST parameters during an active
session.
Modified TRHOSTIN so that it is possible to redirect input
into it, and added a sample response file TRHOSTIN.RES.
3.18 Corrected a problem with TR failing to detect a loss of carrier in
the middle of a session.
3.17 Improved CTS handshaking for use with V42bis modems.
Increased printer buffer size to cope with faster modems and
longer propagation delays.
Added direct support for external file transfer protocol programs
such as DSZ.
3.16 Modified TRHOST's ring response code so that the user can choose
to have a string sent direct to the modem instead of having it
"typed".
Added a "private" mode option to TRHOST to allow the host PC to
run with a dead keyboard and blank screen.
Added TRASK (a program like ASK but with a timeout) to replace
TRKEY.
Modified TRHOST to cut down memory usage slightly by freeing
environment space. This could be significant for users who have
very large amounts of environment text.
Updated author's Internet address.
Finally worked out what needed to be done to allow TRHOST to be
loaded high (by QEMM's LOADHI for example) without hanging when
the host should have been rebooted!
3.15 Modified TRHOST so that the "reboot on loss of carrier" option
only takes effect if there has been a successful TeleReplica
session at some time in the past (previously the PC would reboot
when the carrier was lost even if TeleReplica had never been
active, which sometimes caused rebooting to occur at unfortunate
moments!).
3.14 Decided to permit users to purchase the full source code (for
private use only).
Made other minor variations to the handling of foreign currency
registrations.
3.13 Removed the messages about synchronizing the baud rate and sending
the password, and replaced them with a beep so that line noise does
not disturb the screen text so much.
Modified the file transfer timeout process so that TR keeps on
waiting for the transfer to commence until the user presses a
key, rather than just waiting a specified time period. [Note
that this eliminated one parameter from the .TR file.]
3.12 Added a new program, TRREMOVE, to remove TRHOST from memory.
Previously this could be done by TRHOSTIN, but having a
separate program avoided any danger of inadvertently modifying
TRHOST parameters...
3.11 Added remote printing capability. [Note that this required an
extra parameter in the .TR file.]
3.10 Changed TR.EXE and TRGET.EXE so that directories were created
as required during file transfer.
