Why does my Kaypro drop characters above (insert baud rate)?
(Jeff Wieland, Stephen Griswold, Don Kirkpatrick) The basic problem is that updating the screen takes too long and some incoming characters are missed. The exact baud rate where characters begin to disappear depends on the configuration of the Kaypro and the terminal program. Generally, the older non-graphic Kaypros will run at a much higher baud rate before characters start to disappear. Stock Kaypros are not interrupt driven and the BIOS ROM has several built-in delays, which demanded too much of a 2x/4x/10’s time. Several things can be done to help the situation. If your Kaypro came with the MITE software package, you can use it for high speed terminal emulation. A Kaypro 2X using MITE can go as fast as 19200 bps. MITE uses interrupts to achieve this. Sometimes the problem can be ignored. A 2X will drop characters at 300 baud using Kermit-80. File transfers work fine at 19200 bps. It is always a good ides to run file transfers in the quiet mode if terminal mode is dropping character
