I ran `ser2net` from the command line with a number of threads and a number= of CPUs seems to max at 100%. The serial output `set2net` sents over the telnet connection has dropped da= ta. Observing the data stream from the RTEMS applications running on the Utlras= cale hardware it seems the dropped data is from the start of a block. The UART h= as a TX FIFO and it is being used.=20 Note, the `rtems-test` command uses Python's `telnetlib` to connect using t= he telnet protocol. --=20 You are receiving this mail because: You are the assignee for the bug.=
