Does anyone have any experience of using the PCPI Applicard and Super Serial
card at 9600 baud. I have tried this and found that a lot of characters are
dropped. As the basic Super Serial Card in dumb terminal mode (working
totally in the Apple environment) does not seem to have this problem, I
suspect that the difficulty arises because of slow communication
between the Apple and the Applicard (in character rather than block mode).
One solution, if indeed this is the problem, might be to use the SIO board
which plugs directly into the Applicard. If any one has any other ideas
I would appreciate them.
thank you in advance

At 9600, there really isn't enough time to do much with the data once you've got it (mainly due to the slow 6502 processing). I've managed to transfer information at 19200 baud using the super-serial card, but only if I do the processing myself in assembly language and don't try doing anything related to printing on the screen or writing to any other peripherals. (you might be able to print on the screen using your own routines, but don't try it using the normal apple-bios way, you'll loose characters every time). What language(s) are you using for this? --- John Stanley (john@viper.UUCP) Software Consultant - DynaSoft Systems UUCP: ...{amdahl,ihnp4,rutgers}!{meccts,dayton}!viper!john
