RS-232 Port and ASCII Control Characters

LDS Plus Reference Guide

E-SW-LDSPLUSRG-G

RS-232 Port and ASCII Control Characters

The ASCII Control Characters (00 Hex through 1F Hex) may not appear in the data stream
to/from the Host. However, LXE has provided a method of causing any or all of these ASCII
Control Characters to be communicated to and from the connected RS-232 device.

When the Host wants to send one of the ASCII Control Characters to a standard DOS terminal, it
must place two characters in the data stream for each ASCII Control Character to be sent. The first
of these two characters must always be the DEL character (7F Hex). The second character is
determined by adding 40 Hex to the desired ASCII Control Character. The following chart
indicates how this character pair is selected when a particular ASCII Control Character must be
sent to the RS-232 device connected to a DOS terminal.

ASCII CTRL
Character

+40 Hex

Character Pair
to Send

Null (00 Hex)

00 + 40 = 40 = @

DEL and @
(7F Hex)

(40 Hex)

SOH (01 Hex)

01 + 40 = 41 = A

DEL and A
(7F Hex)

(41 Hex)

STX (02 Hex)

02 + 40 = 42 = B

DEL and B
(7F Hex)

(42 Hex)

ETX (03 Hex)

03 + 40 = 43 = C

DEL and C
(7F Hex)

(43 Hex)

EOT (04 Hex)

04 + 40 + 44 = D

DEL and D
