[comp.sys.mac.programmer] The #@$#@ Serial Port

jpf10694@uxa.cso.uiuc.edu (Joseph Peter Fleck) (06/10/91)

Hey,
	I need some help with a program I'm writing... I'll make this
quick... It accesses the serial port and when I finally got the program
done and pretty much debugged, I sent it out to a friend to beta test it.
It immediately froze on him when it tried to send some initialization
strings to his modem... Well, I narrowed the problem down to that
the program will allow things to be FSWrite (written) to the modem only
if CD (carrier detect) is forced on the modem.  If not, it freezes on 
that line.. Does anyone have ANY ideas on why this is?  I have thoroughly
scanned IM II & IV with no luck.  E-mail is preferred, but a reply here
would be fine, too!
	Thanks!
