- I have no practical experience with loaclTalk, but I thought that the Mac
- serial
- ports could only be driven by the mac to 56kbps reliably. To run at
- localTalk
- speed of 212kbps the port has to be externally clocked which is one of the
- functions of the box. This would seem to imply that the null modem setup
- might
- work, but kinda slow.
- Are my ideas on this correct?
