Hi All!
 Happy Holidays to you and yours..
 I've been having a problem with my Optima 28.8 V.34/V.FC+FAX.
 This an external modem that has worked well for years (still does)
 Ok, heres the trouble.
 I have now an ISDN line installed. There are 3 regular Analog lines
 in the house already. The ISDN Modem is an external Motorola Bitsurfer
 Pro. It has ports for 2 analog lines on the back. (both work fine)
 The Pc is a Pentium 120 with 32 meg HS ports the works. Using Win95,
 Dos 6.2 and OS/2 warp.
 The Modem is connected to one of the pots ports on the Bitsurfer. I
 have the ability to switch the lines to regular analog or the Bitsurfer.
  The Local ISP or BBS or whatever connects fine with the straight Analog,
 but, the ISDN pots line takes longer to connect and most times, the Hayes
 sends out garbage after a connect on the ISDN pots line. It DOES sometimes
 work just fine but 85% of the time Junk after the connect.
 If I switch to analog line ONLY, SAME setup on the Pc, it connects great.
 What gives? I thought ISDN was CLEAN and the analog side would follow.
 Do I need a different Init. when the ISDN side is connected? S-registers,
 not sure..
 Anybody hit on this yet? It looks like a baud rate problem but it will work
 if you retry enough.. say 9 times in a row. Ports on the pc have been
 adjusted up, down, locked, unlocked, called Motorola and the latest flash
 rom is in.
  Must be the Hayes?
   Thanx Much,
     Mike
