TNC 360 3 Standard Data Transmission Protocol 8/95
3.1.6 Reading in an offered program
After commencement of transfer, the peripheral unit sends the first program module until the
receiving buffer of the TNC is full. The TNC then stops transmission with <DC3> and awaits
acknowledgment from the user. If the file is to be transferred, the TNC sends <DC1> and the
program is read in and stored. Otherwise the file is in fact read in but not stored. If hardware
handshaking is set, transfer by using the RTS signal is stopped and restarted.
