- MANAGEMENT BULLETIN
-
- The DDN MANAGEMENT BULLETIN is distributed online by the DDN Network
- Information Center under DISA contract as a means of communicating
- official policy, procedures and other information of concern to
- management personnel at DDN facilities. Back issues may be read
- through the TACNEWS server ("@n" command at the TAC) or may be
- obtained by FTP (or Kermit) from the NIC.DDN.MIL host [192.112.36.5]
- using login="anonymous" and password="guest". The pathname
- for bulletins is ddn-news/ddn-mgt-bulletin-nn.txt (where "nn" is the
- bulletin number).

- CODEX Modem Procedures
-
- 1. The CODEX modem used as the replacement for the AT&T dial-in modem does
- not work the same way as the AT&T modems did. The AT&T modem and TAC
- combination required that the user send a control Q to determine the
- connection speed. The TAC would then display the banner and be in the
- ready state to respond to TAC commands. The CODEX modem and TAC
- combination does not require the control-Q and, under some circumstances,
- may not respond to a single control-Q.
-
- 2. If you experience problems, the following process appears to consistently
- correct the problem.
-
- (NOTE: Script files MUST NOT contain TAC or account passwords
- --that is a violation of MILNET access procedures!)
-
- Using a script file that currently works with the AT&T modems, add a 5-
- second pause before issuing the control-Q character. This should allow
- users to connect without any further action or deviation from former
- procedures.
-
- 3. This is a "quick fix" solution and may have significant impact on
- current users who do not know how to maintain their own script files.
- However, at this point, it is the only solution DISA has in hand.
- A request will be made to DISA Engineering support to determine if a
- better and more universal solution exists.
-
- 4. Any MILNET user having difficulty connecting to a MILNET TAC should
- contact the NIC Help Desk for assistance. The Help Desk telephone # is
- 1-800-365-3642 (1-800-365-DNIC).
