We all have to accept that doing any sort of accurate timing operation on a PC is futile - whether Soundacard, serial port or, even worse, by software timing. Therefore some sort of external interface really should be used to resynchronise Tx and Rx data samples . Hmm, perhaps not all is lost. The Pentium II class CPUs and the Athlons do have the so-called Performance Timer, an hardware timer that can be queried through Windoze APIs, with resolution around 1 usec. This however would rule out old Pentiums, 486 and the AMD K6, which do not have that counter. 73 Alberto I2PHD |
