Version 4.04. Moscow, March 26th, 1993


1. OH relay save routine  has  been  added.  It  prevents  modem  to  go
   off-hook while the line is ringing (and there's high ringing  voltage
   on the line). In case of permanent ring (longer than  3  sec),  modem
   will go off-hook anyway. This routine may cause a delay  for  upto  3
   sec in performing of ATA, ATD, ATH1 commands.

2. ATW2 responces have been changed. If MNP long responces  are  enabled
   (AT\V1), modem will report "CONNECT <DCE speed>/REL" in case it's MNP
   or V.42 connection and "CONNECT <DCE speed>" otherwise. If  MNP  long
   responces are disabled  (AT\V0),  modem  will  report  "CONNECT  <DCE
   speed>" regardless of connection type (reliable  or  not).  Pls  note
   that MNP long responces are disabled  after  ATW2.  If  you  want  to
   enable it, you should enter AT\V1   a_f_t_e_r    ATW2.

Version 4.05. Moscow, April 22nd, 1993


1. SC11043 support has been added.

2. Previous versions have a bug in AT&F  command:  S100  thru  S111  are
   loaded with saved in NVRAM value rather than _factory_ defaults.  Got
   fixed.

Version 4.06. Moscow, April 30th, 1993


1. External modem serial NV RAM handling routines have been fixed.

Version 4.07. Moscow, May 26th, 1993


1. AT%Bn command has been added to set DCE speed limit:

        AT%B1   - 300 bps
        AT%B2   - 1200 bps
        AT%B3   - 2400 bps

   Speed gets limited to the AT%B value or DTE speed value, whatever  is
   smaller.

   This allows a user to lock COM-port at a high speed  (9600  bps,  for
   example), call another modem in Bell 212A mode (1200  bps)  and  take
   advantage of the V.42bis or MNP data compression.

2. AT\S (NEW_CMD.ASM) speed limit (AT%B) display has been added on place
   of AT&R. AT&R  is  not  supported  although  it  was  shown  in  AT\S
   printout.

Version 4.08. Moscow, July 1st, 1993


1. CPM_OPT got overwritten during NV RAM procedures called  from  ATD_S.
   That caused wrong modem responces during ATDS (dial  stored)  command
   execution. Fixed in 4.08.

2. Leased line switch support added  (MAIN.ASM,  CPMDEF.ASM).  Use  GREP
   LEASED_LINE_SWiTCH.

Version 4.09. Moscow, July 9th, 1993


1. Hidden time-out command added. Hidden time-out is located in  NV  RAM
   and replaces S7 time-out if <> 0. If hidden tmo is 0, S7 is in effect
   (this is factory default).

        Format: AT*T?   -- displays hidden time-out value
                AT*Tnnn -- set hidden time-out to nnn seconds. nnn is  a
                           dec number in range 0 - 255.

2. Archtek control panel support added.

Version 4.10. Moscow, Jan 3rd, 1994


1. AT\Pn, don't accept n > 2. Module NEW_CMD.ASM, near MNP_P:

2. Disable incoming ring detection for 2 sec after modem  goes  on-hook.
   Modules MAIN.ASM, FUNCTION.ASM, removed conditionals near DLY_OH.

Version 4.11. Moscow, Nov 18th, 1994


1. Power-on leased line mode, entering +++  will  result  in  the  modem
   ERROR message sent repeatedly, until the leased line  switch  set  to
   OFF. Fixed.

2. Auto-answer switch will set S0=1 if on, otherwise S0 will  be  loaded
   with the NV RAM value  (prior  versions  cleared  S0  if  auto-answer
   switch was OFF).

3. Added FRONTP_FLAG word and VD_HANGUP  bit,  CPMDEF.ASM.  The  bit  is
   reset in MAIN.ASM, near ENDLINE, and set when the modem is  executing
   command. V/D press will result in modem hangup (like &D2 DTR  on/off)
   when the bit  is  reset  and  in  ATD/ATA  depending  on  O/A  status
   otherwise. Thus, the modem will respond to V/D press more correctly.

   Before the change, we judge by the ONLINE bit, and V/D press  doesn't
   force modem hangup during dial or handshake.
