The ttcp_orig subdirectory contains the original +UNIX program which can be compiled and run on your host machine. + +The RTEMS version of the test program is a little clumsy to use. You +have to edit the rtems_ttcp.c source file and change the ttcp_argv +array of strings to set the arguments you want passed to the ttcp +task. + +It does work, though. The best throughputs I've seen so far are: + 68360 card can transmit a TCP stream at 198 kbytes/second. + 68360 card can receive a TCP stream at 119 kbytes/second. +In both cases, the other end of the transfer was a 486DX2/66 running +OPENSTEP/MACH 4.1. + +One noteworthy item is that I was able to get the UNIX test program +running under RTEMS with no changes to the test program itself. The +entire UNIX source file is included, without changes, into the RTEMS +source file. |
