I got Mini vMac to start up MacTerminal 1.1.

It appears that the only flow control it supports is either Software (Xon/Xoff) or none. Software flow control vs hardware isn't something I have tested personally back to back. I do know that if you have an option for hardware flow control (CTS RTS), you should used it.

I would be quite pleased to have a go at fiddling with it on a 512K. It seems that it does have an option to send a file as Text but as my Receive option is greyed out (most likely because I have no active connection), you may be correct about binary files only.

I had located MacBinary II 1.0.1 ...around the web. It only works with System 6 and above. This is why I don't care much for MacBinary archives. BinHex 4.0 just...works and is multi-platform. I found a worthy quote that I'll put in the next (and final) release of the Guide (source is the Handbook of Data Compression):

Before delving into the details of the format, the reader should understand why such a format is used. ASCII is a 7-bit code. Each character is coded as a 7-bit number, which allows for 128 charactes in the ASCII table. The ASCII standard recommends adding an eighth bit as parity to every character for increased reliability. However, the standard does not specify odd or even parity, and many computers simply ignore the extra bit or even set it to 0. As a result, when files are transferred in a computer network, some transfer programs may ignore the eighth bit and transfer just seven bits per character. This isn't so bad when a text file is being transferred but when the file is binary, no bits should be ignored. This is why it is safer to tranfer text files, rather than binary files, over computer networks. The idea of BinHex is to translate any file to a text file.

Still, if you say PackIt works well, then I will investigate it, and note its type & creator information for reference alongside the other mini-library of type & creator codes.

You should try out MacTerminal 2.2. It's the last version that will run on a 128K and should be just dandy on a 512K. I didn't get a chance to play with it before my LCII went KAPOW. :disapprove:
