In StreamDevice I had seen no reason to have longer Buffers than the

link. But when the limit is raised or removed, I will change the code.

It’s seems to be a limitation in the protocol parser of the stream module not within the EPICS stuff:

In

StreamEpics.cc:

Line 407:

long streamInitRecord(dbCommon* record, const struct link *ioLink,
     streamIoFunction readData, streamIoFunction writeData)
{
     char filename[80];
     char protocol[80];
     char busname[80];
     int addr = -1;
     char busparam[80];
     memset(busparam, 0 ,sizeof(busparam));

buffers are fixed to 80 character sizes

This happens when the link string is too long. It can have only 78
chars (80 including @ and terminating null byte). This is a
limitiation of EPICS.

FYI, this limit is raised to  254 characters in Base 3.15 series and
removed entirely for 3.16 series.
