I can¡¯t say for sure as they are from a PUT tape we don¡¯t have, so don¡¯t have the matching ¡°memo¡± file which lists the fixes and the problem they fix.
However it looks likely that they are? concerned with line errors, which probably don¡¯t occur under Hercules
I have a question for those of you who know VM/370 "internals". There has been some activity recently on the Moshix Discord channel regarding UTS (Amdahl Unix), and to make it possible to dial to the UTS virtual machine via a 2703 connection, some changes to DMKCNS are apparently necessary, namely the following modifications are commented out from DMKCNS AUXR60:?
?
?R13158DK 625 UV05563 LOOP IN CNS AND IOS ON IFCC CC=1
?R13198DK 625 UV04984 NO DISCONNECT IF IN ERROR RECOVERY
?R12733DK 625 UV05520 CC1 LOOP SOUNDING ALARM TO POWERED OFF D/T3215
?R12126DK 624 UV02926 D/T4331 CA UNIT CHECK NOT HANDLED CORRECTLY
?
If I am right, these modifications come from IBM, so I wonder to what extent their suppression can affect the behavior of other virtual machines. Any comment?
