Can anyone tell me if it's possible to get a cable from mac serial port
to modem that supports hardware handshaking?  If so, where?  Local stores
I've asked don't understand my question.

My intent is to use it with my telebit t2500 modem.  Currently, with software
flow control, and connecting to "dumb" modem on other end, and if errors
occur and resend requested, it gets way ahead of itself and very very very
slow.  So I have to set it to no flow control (s66=0) and manually set telecom
program to whatever baud rate, then set it back, etc. -- which is a pain.
White Knight manual claims it will support hardware handshaking, but the
checkbox in cmd-U dialog is greyed out -- presumably, because my cable is
not wired to support it. (?)  Manual does say you need a special cable.

Also, I use dial-in to shiva netserial with same model telebit t2500 modem.
I wonder if that will work with hardware handshaking?  Can I mix sw/hw?
Telebit manual seems to say yes:  s58/68 can be set to use "both".

If you can clear this up for me, I'd sure appreciate it!  :)
