Re: Super Serial Card II Schematics/Dox Needed

["Circus" <circus123@hotmal.com>]

so far it is working except that to get a particular baud rate I have to set
it for the rate that is the next higher up. so to get 19200 I have to set
the commodore to 38400. I have played with the jumpers with no luck so far.
however it does seem to be working correctly and I have transferred files at
19200 successfully.

The schematics can be found by using google and searching for "swiftlink
schematics" or something similar..... They all call for the faster crystal.
