Using TERM or TinyTERM over a serial connection, with the emulation set to ANSI, the display is OK, but the arrow keys don’t work. With the emulation set to VT100, the arrow keys work, but instead of lines, it displays the letter d repeatedly.

To solve both the arrow key and line draw problems, check to see if the UNIX tty port is set to a word length of 7. If it is, set the port for a word lengthy of 8, 1 stop bit and no parity. The host application is sending 8-bit sequences for the line draw characters. With these changes, VT100 emulation will work.
