If you want to transmit a binary file from one computer to another over a communications line and you don't have KERMIT, or MODEM7, or TRANSF available at both ends, you will find the programs BITOAS and ASTOBI useful. BITOAS converts a binary file to an ASCII printable file (with imbedded checksum information) using a 2-to-3 compression algorithm. ASTOBI converts the resulting ASCII file back to the original binary form. To send a binary file 1. Transmit the source of ASTOBI to the remote system, and compile and link (taskbuild?) it. 2. Run the binary file through BITOAS on your local system. 3. Transmit the resulting ASCII file to the remote system. 4. Run the ASCII file through ASTOBI on the remote system to reconstruct the original binary there. If any transmission errors occured, ASTOBI will report the problem but will not be able to fix up the file, so you will have to transmit again.
