Device Configuration in NATCONFG

Logical net data devices are configured with the IONET flag byte, all other flag and value settings must be made as in the sample definition given below. The module entry is VCNETTO, additional device entries must be specified with WXTRN=OFF. The settings of FLAG1, FLAG2 and RTAL must be according to the example below.

If the data delimited option (NEDLM) is set, the delimiter character which separates the fields in the value buffer can be set by using the BEL keyword subparameter of the NTDVCE macro.

The TTYPE is NETF. The protocol options are set as follows:

  • The value buffer structure is fixed (without delimitation between the fields).

  • Format buffer, extended format buffer and attribute buffer options are set.

  • The cursor position is in the field number notation.

Message line and PF-key line are suppressed.
