[comp.sys.mac] Problems with RAM serial driver

milo@ndmath.UUCP (Greg Corson) (12/18/86)

I am having a strange problem with a terminal program I am writing...I 
recently tried to put in a switch to allow the user to change from the
modem port to the printer port.  When the user changes I first do a
RAMSDCLOSE on the modem port...then a RAMSDOPEN on the printer port.
Neither of these operations generate an error, but when I try to do anything
with the printer port (write to it, set buffer size..etc) I get a "device
not open" error code back.  If I switch back to the modem port everything
works fine again.  Any suggestions as to what might be causing the 
problem??
