21<h6>Why choosing the CC90-232 interface ? There is an interface compatible with Thomsons of last generation, isn't it ?</h6>
22
23<p>Yes, there is an interface which works with TO8, TO8D and TO9+ : the RF57-932 interface. But it's hard to find it.</p>

27<h6>Is it possible to use the RF57-932 interface with CC90 program ?</h6>
28
29<p>No. Hardware registers are not similar. CC90 program won't then work.</p>

33<h6>Why a 38400 baud speed ?</h6>
34
35<p>We could choose a higher speed, like 57600 baud, for example. First, a 6809 cycle can't be divided, and a 57600 baud speed need a temporization of 17.333 cycles. Next, a slower speed gives the opportunity to calculate the CRC during  the transmission, and to be more comfortable in loops.</p>
