The idle condition of the TTL RxD signal is +5V. This condition also causes the Ap863-TTL to wake
up and prevents it from going to sleep. If the Ap863-TTL is required to go to sleep then the host
equipment must be configured to output 0V.

CHARACTER PRINTING
Several character fonts are supported, the default 32-column character set being formed from a
24x10 dot matrix. The standard 224 IBM® character set (Code Page 437) includes graphics
characters, which are extended to link up in both axes where appropriate. The character set has been
modified to include the Euro symbol (‘€’) at position 80H (128 Decimal), in place of the usual capital C
with cedilla (‘Ç’).
Text can be printed in various combinations of single or double width, single or double height,
inverted, underlined, and with other attributes. Text and dot- addressable graphics can be mixed
within a line.
