* Defererence pointers after any paranoid checks, not before.
*
* (21/Jun/2003) Erik Nygren
- * Added support for Home Electronics Tira-1 IR tranceiver using FT232BM chip.
+ * Added support for Home Electronics Tira-1 IR transceiver using FT232BM chip.
* See <http://www.home-electro.com/tira1.htm>. Only operates properly
* at 100000 and RTS-CTS, so set custom divisor mode on startup.
* Also force the Tira-1 and USB-UIRT to only use their custom baud rates.
* Minor whitespace and comment changes.
*
* (12/Jun/2003) David Norwood
- * Added support for USB-UIRT IR tranceiver using 8U232AM chip.
+ * Added support for USB-UIRT IR transceiver using 8U232AM chip.
* See <http://home.earthlink.net/~jrhees/USBUIRT/index.htm>. Only
* operates properly at 312500, so set custom divisor mode on startup.
