Xmodem / Xmodem1K
Supports Both CRC and CheckSum Error Correction
Xmodem.exe has a built in communications manager and
doesn't need any type of fossil, in fact you should make
sure you turn the fossil OFF if running it on a BBS
that uses a fossil.
Xmodem requires a number of command line switches:
-B, -P, {-R or -S}
-B <Baud Rate>
-P <Port Number>
-L <Serial Lock Rate>
-R <FILENAME> Receive file, Filename may include full drive
and path. E.G. C:\osiris\uploads\newzip.zip
-S <filename>, Send filename. May include full drive and
path. E.G. C:\OSIRIS\ARCHIVES\NEWZIP.ZIP.
-K , Use Xmodem1K (1024 Byte Blocks, sometimes referred to as
Ymodem).
-N x, with x being the node number in use. For use on Osiris
CBIS systems only. Xmodem will show the name of the
caller as well as where he's from if this switch is used.
-B, supported baud rates 300 - 115,200 Baud.
-P, Supported Com Ports, COM 1, COM 2, COM 3, and COM 4.
(COM1-8 if used with OSIRIS.)
-L, Supported Locked Baud Rates, 300 - 115200 Baud.
NOTE: -R or -S MUST be the last
parameter on the command line. As soon as
Xmodem encounters either one of these two
switches, it will begin to either Receive
or Send.
Xmodem Technical Reference Manual Page 2
There must be one at least blank space between The switch and
the parameter..ie. -B<BLANK>2400
The -L switch is only for those that do not have COMx= set in
the environment. If your running Osiris then Xmodem will use
the COMx= automatically.
