Many Macintosh communication programs, such as MacTerminal, MicroPhone,
Smartcom II, Kermit, MacBLAST, VersaTerm, and so on, have VT100, VT52,
VT102 terminal emulation. These programs also have file transfer
protocols, such as X/Y/Zmodem, Kermit, MacBinary, and so on.
Most UNIX machines support these types of terminal emulation. As long as
your UNIX machine has the same file transfer protocol (such as Kermit, or
X/Y/Z Modem) as your Macintosh software, there should be no problem doing
file transfers.
