that is not a valid baud rate... is this using a FOSSIL or no?

FWIW: the valid baud rates are...

    110, 300, 600, 1200, 2400, 4800, 9600, 14400, 
    19200, 28800, 38400, 56000, 57600, 115200

some serial ports support these higher rates

    128000, 153600, 230400, 256000, 460800, 921600

but they are no valid for our old school BBS operations... in fact, locking
a serial port to 115200 in one FOSSIL driver requires one to use 11520
because the baud rate speed value is stored in a word (0..65535)...

you should not "float" your serial connection... you should run
it with a "locked" port rate and then let the (virtual) modem
handle the actual connect rate with the remote on its own while talking to
the local "port" at one specific rate...

i don't doubt they won't work with an invalid baud rate like that...

that's weird... unless there's a locked port rate setting...

ok...
