The Extended XMODEM protocol - Adontec

ADONTEC Extended XMODEM
SuperCom specifics
SuperCom was the first library used to develop this protocol.
The protocol is receiver driven and the SuperCom implementation offers the following constants to
select the protocol option for the receiver:
PROTOCOL_EXMODEM_01K
PROTOCOL_EXMODEM_05K
PROTOCOL_EXMODEM_1K
PROTOCOL_EXMODEM_2K
PROTOCOL_EXMODEM_8K
PROTOCOL_EXMODEM_32K
PROTOCOL_EXMODEM_64K
The above constants can be used with the receiving function e.g. RS_RXFileEx or, in case of the
ActiveX API, the property Protocol in order to select the preferred option.
The SuperCom transmitter can be called with any of the available protocol options (e.g. XMODEM,
XMODEM/CRC, XMODEM/8K to XMODEM/64K). It will consider the request received from the
receiver.
An unaware third party transmitter will probably start with XMODEM or XMODEM/CRC,
options that are well supported by the Extended XMODEM receiver.
The SuperCom transmitter is started with RS_TXFileEx or, in case of the ActiveX API, the property
FileTransmit.
The SuperCom receiver is started with RS_RXFileEx or, in case of the ActiveX API, the property
FileReceive.
More details about using this protocol with SuperCom can be found in the product documentation.
