Not true. The line speed on the line description on V24 ports DOES limit
and control the transfer rate. You can test this out by setting your modem
speed to follow DTE (most defaults do this) and you'll notice the connect
speed change if you adjust the AS400 line speed (again assuming your modem
is not set to return a fixed connect rate). This was an important setting
prior to RISC where the only flow control settings available for async data
transfers was XON/XOFF. In these cases you had to watch for matching
DTE/DCE speed settings or risk modem buffer overflow where you'd lose data.
