Network Transport Protocol (PMERR) Error Messages
10 Network Transport Protocol
(PMERR) Error Messages
The following errors are returned by Transmission Control Protocol
(TCP) as the 32-bit integer “PMERR” parameter in calls to IPCCHECK.
They are also found in the “PARM” field of the TCP Statistics, PM
Deactivated and PM Deactivated with Error logging entries.
NOTE The Network Transport is technically not part of network services; it is
a subsystem of the NS links. However it is included here because it is
available to the user.
