Need advice on USB/fast serial port!
Having an ISDN external modem and the possibility to use two channels
simultaneously, gives the theoretical speed of 128 kbps. However, the
UART's 16550A on the motherboard have a maximum speed of 115.2 kbps.
Including overhead the transfer speed is further reduced. Measured
speed are 62 kbps for one channel and 89 kbps for two channels.
What to do?
Looking around little gives the alternatives (prices vary from $40 to $80):
1. Installing an ISA serial port card with higher speed (interrupts).
2. Installing an PCI serial port card with higher speed.
3. Installing an USB to serial port converter.
The computer has an USB port available. Where can I find USB software
supporting this? Any appropriate modem software?
Opinions? Recommendations? Experiences?
