Cts/Dsr; Intercharacter Delay; Swb - Switch B Command - Magtek MICR Plus Technical Reference Manual

MICR PLUS, RS-232

CTS/DSR

When CTS/DSR (Clear to Send/Data Set Ready) is set to Ignore, the MICR Plus sends data to
the host without waiting for the CTS and DSR signals to be active. When CTS/DTS is set to
Use, the MICR Plus waits for the CTS and DSR signals to be active before sending data.

Intercharacter Delay

The intercharacter delay is used to increase the time between characters transmitted from the
MICR Plus. The delay is equivalent to the transmission of one character. This parameter affects
character rate but not baud rate (i.e., each character takes the same time to transmit but the time
between characters is increased).

SWB - SWITCH B COMMAND

The SWB command controls the message format, shown in Table 4-2. The data for this
command consists of 8 ASCII bits ("0" = hex 30 and "1" = hex 31).
To execute, send the SWB command as follows:
SWB 01010101<CR>
or
SWB <CR>
When sending data, all 8 bits must be provided. The MICR Plus will execute the command but
it will not reply. The new settings become effective immediately.
If no data is sent, the MICR Plus responds with the current settings for SWB. To make this
command permanent, use the SA command described below.
