It is taking me 2.5 *hours* per 140k .dsk file from a PC. This seems rather
excessive. I used the pinouts listed in the transfer faq to build a
combination 2gs high speed modem cable/null modem adapter in one cable (faq
#20, end of question 6 answers, using dsub9f on the PC end).
Now doing the math, assuming 1 bit per baud at 9600 baud, 9600 bits per
second at 8 data bits + 1 stop bit per byte means 1066 bytes per second.
140k bytes = 143,360 bytes should transfer in about 2.2 *minutes*. Adding
time for software overhead (error checking) and file saving shouldn't add
2.3 *hours*. Is my math or my cable flawed? The disks do work and no errors
are reported during transfer on either end.
Here's the pinouts I used from the faq:

4,8 5 GND
2 7 RTS
1 1,6,8 CTS, DSR, DCD
7 4 DTR
Thanks.
