Re: Connecting AS/400's SDLC PASTHR via Modem?

The problem is with modem setup.
AS/400 adapters (and V.25bis standard) require, that when idle, DSR from a modem
should be off.
(In async world DSR is normally always on.)

Subject:  Connecting AS/400's SDLC PASTHR via Modem?




Hi All,

I am setting up a v.24 modem to dial another AS/400 for PASTHR.  I have
created the line, Controller, and Device.  When I vary-on the line with the
modem connected, it will go to connect pending and then fail and go to
RCYPND.  I can not figure out what is going on.  The message is as follows:

    Message . . . . :   Line UCFSLIN failed. Probable local modem problem.
(C G R)
    Cause . . . . . :   The system is trying to build a session with a
remote
      device and has received an error.  This is probably a local modem
problem.


     The error code is X'44001010':  Data set ready (DSR) was active from
the
     modem before the data terminal ready (DTR) was brought active by the
system.

I am unable to determine where the error is, the modem or my 400 configs.
If anyone knows of any manuals that I can use to look this up I would
greatly appreciate it.  I haven't been able to find anything on this.

Thanks for any assistance,

Fred
