- I've been having a problem using the Rev. C m68360 Smc in uart mode. The
- smc receives a garbled character about 1 in 20. This only occurs with a
- Wyse WY-520/ES dumb terminal. Using a scope I have demonstrated that the
- wave form of the transmitted character from the Wyse is very poor, with
- low voltage and slow rise time. Apparently this is so bad that the smc
- has problems with it. The m68360 Scc handles this ok, however.
-
- I found an errata referring to the smc's inability to handle "short
- start bits".
-
- Does this ring any bells for anyone?
