HP 75 and the PIL-Box

Christoph, how can the additional TCP-IP traffic have such a desastrous impact on the overall performance? Since the pure combination Emu71Win - ILPer, also linked by TCP/IP, is extremely fast, it seems to be a problem with ILPILBox ( Version 1.1 ) ?

TNX for your test. I agree that the problem is caused by ILPilbox.exe. The serial implementation for the PIL-Box hardware inside ILPilbox.exe is different from the implementation inside ILPer.exe because with ILPilbox the PIL-Box hardware itself can operate as controller or as device, whereas with ILPer only as device.

Edit 01/06/14: I will fix the bug soon. Latest tests more or less show the same transfer time like the PIL-Box directly connected to ILPer. The transfer speed with PIL-Box as controller (Emu71/Win as controller operation) is a little bit slower comparing to the PIL-Box as device/listener, but no speed changes to ILPilbox version v1.2. This is a software design issue of the actual ILPilbox program.
