I have recently tried to upload files to various machines without
success. Using a MacII with a Hayes 2400 modem and White Knight
software, I get so many resends the transfer bombs out totally.
To trouble shoot the problem, I have checked all applicable modem
and terminal emulator settings as well as calling Ma Bell to clean
up any line noise. In addition, I have no problem down loading
(receiving) files from any of the bulletin boards I've accessed.
This lead me to believe I may have a hardware problem at the
modem serial port in my MacII. I checked this by hooking up to a
friend's SE directly by cabling the two modem ports together (no
phone line, no modem factor). I could receive files again w/o
any problem, but sending files again bombed out due to the high
resend error rate.  Is my guess correct as to this being a 
hardware problem? Any suggestions on fixing it? I don't have
Applecare (I'm too cheap for that) and am wondering what it would
cost for a technician to fix it.
