Speed problems with VISA for serial com. on some PCs, speed diff. up to 10 x

[mair]

Using VISA driver for serial communication with 115kB results in the following problem: On some machines the transfer speed is ok, in other the speed is up to 10 times slower, without any reason, but it works. The problem occurs under WIN 98 and also under WIN XP. The VISA driver used is the one delivered with LV 5.1.1 and should be 2.5 (or 2.6).
