#Usb to serial driver belkin f5u409 software
So it seems that XON/XOFF software flow control is not implemented in this driver, which is derived by sniffing the usb commands issued under Windows98. Both signals are dropped for no flow controlīut asserted for hardware or software flow control. No flow control specific requests have been realizedĪpart from DTR/RTS settings. In this case the Linux driver chosen because of the id is the mct_u232.c. The Belkin F5U 109 seems to be a device of fairly old design, so perhaps the F5U 409 with the same usb vendor:device id is similar. Note that all of these parameters are set in stty: ixon imaxbel iutf8 opost -olcuc -ocrnl onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0īs0 vt0 ff0 isig icanon iexten echo echoe echok -echonl -noflsh -xcase -tostop brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr icrnl ixon ixoff -iuclc -ixany Time = 0 -parenb -parodd -cmspar cs8 -hupcl cstopb cread -clocal -crtscts -ignbrk Stop = ^S susp = ^Z rprnt = ^R werase = ^W lnext = ^V discard = ^O min = 1 Kill = ^U eof = ^D eol = eol2 = swtch = start = ^Q Speed 9600 baud rows 40 columns 80 line = 0 intr = ^C quit = ^\ erase = ^? Stty configuration on the Ubuntu machine: stty -a TEL.COM settings on the PX-8: Baud: 9600, Char Bits: 8, Parity: NONE, Stop Bits: 2, RTS: ON, Flow Control: ONĮxample of this issue when I attempt to output command history: historyĢ xprt TEM=Vvj9s9ds9j3oin so nat1 machine I have attempted to set this up on another laptop running Debian 10 but get the same behavior. I am using systemd to enable a console on USB0 with systemctl start Do I need to configure flow control with systemd? Is there some place other than stty I need to configure parameters for ttyUSB0? See below for terminal parameters I have configured on the PX-8. On the PX-8 I am using terminal emulation software called TEL.COM. See below for sample output of the issue.įor context, the computer I am using to connect to the Ubuntu laptop over RS232 is an EPSON PX-8. However, this time setting stty ixon does not resolve the behavior. I have run into the same issue where larger text output will eventually fall apart into scrambled text. Today I am attempting to setup a serial console login prompt on a laptop running Ubunutu 20 with a Belkin F5U409 USB serial adapter. This is related to a previous thread I created about a month ago and which was answered.
