- I really don't have any idea how those modems work.
- I thought the Kermit , Xmodem , Ymodem and Zmodem all worked
- the same way. They would send the data flow to the serial port
- at one end the comm line, and receive the data at the serial
- port at the other end.

- I use the Procomm2.4.2, which doesn't have the Zmodem. But it does
- have the Kermit, Xmodem and Ymodem. and I use the Xmodem and Ymodem
- when I connect to the BBS. on Unix I am using Kermit now,
- but it is slow. The Zmodem package says it also supports
- the Ymodem and Xmodem. So I use sz <file> on Unix to start
- downloading, and use the Ymodem in ProComm to receive <file>.
- According to the Zmodem manual, the Zmodem will auto down shift
- to Ymodem, if it finds the other end doesn't support the Zmodem.
- However, nothing is transmitted in this way.
-
- Since all the data flow should be transmitted thru the serial port
- when we use the modem to connect to the Unix, I doubt that
- the Zmodem had sent the data to somewhere else, not the serial port.
