Default Verbose Mode: Enabled (0x01)
Setting this register to 0x00 will suppress the start-up message, including firmware version, which is sent to
the UART when the module is reset. A value of 0x01 will cause the message to be displayed after reset.
By default, the module start-up message will be displayed. The non-volatile counterpart, regSHOWVER,
has no function.
Table 16, Verbose Mode Settings
Default CSMA Enable: Enabled (0x01)
Carrier-sense multiple access (CSMA) is a best-effort delivery system that listens to the channel before
transmitting a message. If another Wi.232 module is already transmitting when a message is queued, the
module will wait before sending its payload. This helps to eliminate RF message corruption at the expense
of additional latency. Setting this register to 0x01 will enable CSMA. Setting this register to 0x00 will
disable CSMA. By default, CSMA is enabled.

Startup message will NOT be displayed upon reset or power-up
Startup message will be displayed upon reset or power-up. This is a
blocking call, and any incoming UART data will be lost during the
transmission of this message through the TxD pin. All UART
commands must be sent after this message has completed.
Startup message will be displayed upon reset or power-up. This is a
non-blocking call. Any incoming UART data will be buffered, and
incoming UART commands will be processed. If a change of baud
rate is commanded while the startup message is being output, the
current byte will finish at the current baud rate, and subsequent bytes
will be transmitted at the new baud rate.
* Available in 250-R firmware 1.1.0 and newer only.
