Sportster setup

In order to configure the software properly with your Sportster, issue the 
following command in terminal mode:  "AT&F&B1&H1&R2&A3&K3X4S11=38".  After 
getting the "OK" response, issue an "AT&W" to write it into NVRAM.  All of your 
initialization strings in your communications packages should read "ATZ", along 
with the carriage return symbol (different for each software package.  If you do
not want to write the string to your NVRAM,  use  the above init string in your 
software configuration. Do not use the &W.


"&F" - Reset to factory defaults
"&B1" - Lock DTE (computer to modem) speed at the speed of last AT command.  
This is necessary for high speed modems in order to use data compression.  It is
also necessary if your connection rate does not match your DTE speed (i.e. port 
speed at 19200 in software, and you make a 14,400 connection.  If this happens 
with &B0, you'll get garbage).
"&H1" - Hardware send flow control.  Uses the CTS signal to regulate.
"&R2" - Hardware receive flow control.  Uses the RTS signal to regulate.
"&A3" - Extended result codes display.  Enables the modulation, error correction
and data compression types the modem has connected with.
"&K3" - Selective data compression.  If you cannot establish a V.42bis 
connection, it will not attempt an MNP5 connection.  Useful when transferring 
already compressed files (ZIP, ARJ, LZH, etc.).  V.42bis is fast enough to not 
slow down the transfer if the file is already compressed.  MNP5 will drastically
slow the transmission.
"X4" - Extended result code set.  Enables the modem to report the line 
conditions for "BUSY", "NO DIAL TONE", and "NO ANSWER".  
"S11=38" - Reduces the time delay in between dialing tones.  
"&W" - Write to the modem's non-volatile RAM.  Each time you reset the modem 
with "ATZ" or recycle the power, it will come up with the parameters stored in 
NVRAM.

In your software package, choose a port speed of 19200 (115200 for the 28.8), 
set XON/XOFF software flow control to OFF, CTS/RTS hardware flow control to ON, 
DSR/DTR flow control OFF, Autobaud detect OFF.
