If you're going to stay with ProComm, do follow through and add Zmodem. (either DSZ or PCZ... PCZ is free) -- Roy M.

The one you left out, in my book, is best for single or multiple
files. ZMODEM.

I like kermit for most jobs. It's a little slower than Zmodem, but In my experience more reliable. Also, Kermit with long packets erodes Z's speed advantage. -JT

My brother once set up a download using ZMODEM. He came back an hour later expecting to be logged out. (Autologout when download completed.) But the modem was still chugging along with a block size of 1 byte! He quickly brok out and used XMODEM. Turns out if ZMODEM feels too many errors are occuring it decreases the block size to reduce retransmission time. But if the trouble clears up, it doesn't increase the size. What likely happened is the phone got picked up, giving mega noise, and dropping the block size. Otherwise ZMODEM is exceptionally fast, unless you are using MNP5 as well. (The two blocking processes can interfere with each other) in which case there's a YMODEM varient for that reason. SEALINK and TELELINK also work well if Y or ZMODEM are unavailable.
