I have a problem using the Apple as a dumb terminal at 1200 bits per second. I am using a short assembly language program on an Apple IIe that monitors the serial port and Apple keyboard port and writes to the screen using the firmware routine at $FDED. The problem is during CR/LF sequences several characters are lost. I want to know if there is a different subroutine I should be using or do I have to write my own display driver. Suggestions or comments are welcome. Ron Wolenty (AT&T Consumer Products) Indianapolis, IN

From: Doug Gwyn (VLD/VMB) <gwyn@BRL-VLD.ARPA> The code that scrolls the display is taking too long to keep up with 1200 baud. This is a standard problem, especially with 80-column cards. The solution is to write your own display code (use modem interrupts or poll the modem port frequently).
