-> You could do that if the data you were sending used that character

-> up with A-Z (uppercase only) and the requirement to include a FIGure
-> Shift code before sending numbers, and a LETter Shift code to go back
-> to letters again.  In other words, 1930's Teletype.
-> That's not as far out as you might think:  the 8250 UART (I don't
-> know about the 16550) will support 5 bits per character and one and
-> one-half stop bits.  But the UART in your modem probably won't. :-)

-> In fact, though, the bits that are eliminated in the error correction
-> schemes are the start bit and the stop bit - the number of data bits
-> remains unchanged at 8.
Changing the Bit number to have wouldn't help the speed then?
-> I once wrote a terminal program for a color computer that used a
-> home-built modem to communicate using Baudot or ASCII on a radio
-> teletype link.  The program had to convert the ASCII characters to
-> their equivalent Baudot values before sending them to the UART, and
-> naturally, the Baudot back to ASCII when it was received from the
-> UART.  And, you had to include the necessary letter and figure shifts
-> and the carrige return linefeed characters in the data stream as
-> well.
Geez, you must be really good with computers to build a modem and make a
terminal program for it.. How long ago did you do that?
