All, John (VE5MU) and I had a lengthy ALE-400 contact this evening and we decided to experiment a bit. We found that while I was sending mail to John (mail gets stored in Multipsks mailbox) he was able to continue chatting with me.
In other words, he was able to type messages and I was able to see them while my outgoing mail was being transferred. Of course, the conversation was one-sided until the mail transfer completed; Multipsk automatically switched back to two-way ARQ chat mode after that. We also found that it was possible to send mail to each other SIMULTANEOUSLY. This slowed the transfer down of course since the usually short acknowledgments from the receiving station turned into ACK + mail data. Patrick's Multipsk / ALE-400 is certainly unique. The mode itself seems to have a good balance between robust performance and speed. Tony -K2MO
